Steaming disc brakes

[Cryology531]

Thats hot, get it?! :3

[jjripz]

2 easy steps to warp your disks

1.make you disks hot from braking down a hill

2.pour liquid on them

That's how you ruin your disks!

[chalenger42]

Now watch them bend :P

[TheSmokah86]

Beavis and Butthead

[vDefuzed]

@TheSmokah86 Haha LOL :D

[gtpiston04]

Nice way to warp them

[iRTheUnknown]

where is the cool bug?

[wankel7]

Must be a rental bike!



[clovis6000]

Cool vid, and since they aren't my disc brakes, who cares if he fucks them up.

[TheJeepWheeler]

Why not take a pair of Vise Grips to them?

[ChingMan09]

what a waste of water..

[rallyaddicted]

are you crazy???? water on hot brake disks?????? my god...

[rulfryder17290]

next video you must take an egg on it

[liquidyou]

I don't know much about bikes, but I can almost guarantee that's not the way to do it.

[Petegrin1]

You guys have to be Really slow at mountain biking...

[jnisb29]

you could have put that heat to good use and cooked some sausages

[WowOmgStudios]

perfect way to waste perrier.

[TheSippincoffee]

@WowOmgStudios thats san pellegrino

[pklicov]

Mechanical brakes. You must push it earlier than hydro brakes, and must push it much harder to stope and that is the result. You can boil eggs on this one, and with cold water you will ruin you rotor and disc brakes as it is not designed to cool down so fast

[grebo121]

That's normal, these brakes heat up over 450*C. Also i woudn't buy a rotor that deforms by shock cooling, cause offenly on descents i must drive through streamlets, puddles, and what then?

[gonetoworkbbackin5mi]

warp the disc, dodohead

[DKdekes]

as if that doesnt happen to every rotor that goes down a mountain...

[djape48]

omg what a retards. nice move placing that plastic bottle on hot rotor

[drewb1994]

and thats how you warp a rotor :)

[minkyman8]

nd how fast were you going to make them that hot :O

[cheezecake2000]

use the brakes less on the front! use the rear more!

[pepene93]

@cheezecake2000 uh...have you ever been mountain biking? front brakes provide the vast majority of braking power. rears help a bit, but i mostly use them to stabilize the bike. i could easily do without their stopping power

[konrad735]

160 ...;D

[craze75]

well, that's one way to fuck up your disc brakes

[daveandvera]

Totally agree rapidly cooling a disc is almost certain to damage it ,either warping it or it may shatter in a future run as the rapid cooling tempers the steel and makes it brittle!

[cougz82]

perfect way to fuck up your disc haha

[kimchijeegeah2]

learn to use the rear brakes... =| cuz they tend to lock up so you don't over heat.

[Xbox360customUK]

That's why you buy avids!!

[234t11]

aah you can do that sure to this cheap brakes hahaha

[audiocable]

warp rotors for errbuddy!

[laughatyourdumbvideo]

How to ruin your brakes in 1 easy step

[jpmartineau]

Wow. Way to ruin your discs.

[Lambo847]

maybe after your next downhill u\you shouldnt use the brakes so much idiot, thats how warping is caused........ some people..

[Jeff818818]

thats a good way to fuck perfectly fine discs. Good job boys keeping the economy strong now go buy some new ones dumb ass.

[jajajaja404]

lol. they must be so hot because you hold your brakes down all the way down the mountain. dumbass

[X10SIV]

I burnt myself on my rotors in a bail. Thats plenty hot enough to warp.

[1891serru]

Kona fire mountain -05, I have the same bike. Good frame but the rest is so so. The discs are more like 20 §.

[crni195]

you just lost 100 $

[backalackadacka]

nice way to warp ur rotor

[jajajaja404]

thats when you know your using too much brake

[Jahcure420]

HOPE M6 are the best brakes ever made

[flatypus0adventure]

@Jahcure420 one way trip to melted discs haha

[Grrrrrene]

This is a very bad idea. It's the ideal way to warp your disks, which significantly deteriorates braking performance. You cool down one side of the disk much quicker than the other side, causing it to shrink much more than the other (hotter) side, which causes the warpage.

It's the same thing you get in the kitchen when you quickly cool a hot pan under the tap. The bottom of the pan will warp and you get a wobbling pan on a flat surface.

[Jahcure420]

wow, you guys are a genius, what do you expect from hot metal and water? steam? what a science experiment, it's like putting water in a pot, duh!

[kanga1234567]

@Jahcure420 : I think he was just trying to illustrate how hot bike discs can get .... some people don't realise that a pushbike can generate this much heat in their brakes!

[YDX5224]

That would do absolutely nothing to the rotor. It would have to be a hell of a lot hotter than braking can get to to warp. For carbon steel to shatter it has to be case hardened which requires heating to straw yellow (1600degC ish) and then plunge cooling. Then to shatter it would need a huge impact. Remember these are carbon steel not cast iron. It's almost impossible to warp carbon steel by plunge cooling, if it was stainless that's another matter but even then braking wouldn't get it hot eno

[d100x]

@YDX5224 Brakes do get hot enough to warp without putting water on them. Often if a car has serious brake issues, the resulting eccentric motion of the rotor can be felt in the steering wheel. Mechanics may use a lathe to take out high spots on either side of the rotor to make it flat again, assuming there is enough material left to do so.

[diddy150]

@aross1989 u act like u bought it for him. Calm your ass down

[aross1989]

ruined ur brakes u dickhead

[cmowforth]

You're effectively quench-hardening the rotor by doing that. It won't affect the braking performance, but the rotor will become more brittle over time.

[gizmogunner]

DONT DO THAT the discs can and do warp and sometimes shatter

[jeshiescoots]

when expenisve metals like discs for disc brakes get hot they need to be cooled on there own time or they can become brittle and crack so if those still work right after that youy lucky

[TeoZMuff313]

when metals heat they expand like most solids when u pour water on it like that it retracks fast and it will do damage or crack

[TheBiblemen]

gets some hydraulic brakes :)

[pmmM203]

touch it.

[DDFJ1230]

@pmmM203

Maybe thats how they found out it was hot?

[dennismaike]

thats stupid now there gonna bend

[MrZappy101]

You obviously are a very slow biker, and why would you even think of doing that, you just shortened the life of your brakes.

[MrDon191]

sam fing happend with me today lolzzz

[leoncarbon]

wow dude won't that destroy your brakes?

[yzorg]

shock cooling can deform the disk....

[VisualBasicProgger]

@yzorg no. its a lie. really!

[ICQannon]

@yzorg I was about to say that myself... Then again, it's not my face against the ground! :)

[tannalv]

Jävla idiot-finnar... Fin cykel. Den förtjänar en bättre ägare.

[mattievk]

i was in autria last two weeks and i went mountainbiking. I touched the disc :(:(

[Gurmelhorst]

@mattievk painful, but way better than ruining your disc by shocking it with cold water, you can also take a thermometer with you and can check the temperature exactly :D

btw: what brake du you have?

[mattievk]

@Gurmelhorst dont know i rented it :P

[chumba11111]

What a fuckin moron!! Now go and buy some new rotors cuz u just warped those ones

[highfencejumper]

Good way to warp a rotor noob!

[kingkrab98]

great job ruining an already ruined bike

[jhoags92]

For those of you that are worried about the water and the heat differential; I pitty the foo.

Water doesn't affect you're pads, oils are what contaminate them. And those rotors are designed to not warp under high and low temperatures.

They'll be fine. Settle down.

[jellyfishin29]

if your going to fuck your rotors then u might aswell flop your cock onto it,then you will know if it's hot!

[salemcripple]

great way to warp your rotors there! 

[snowapeproductions]

that is the dumbest thing you can do to your rotors aside from hitting them with a hammer. You need to be running 203mm rotors if yours are getting that hot your probably boiling your oil too. Overheating can even cause caliper warpage.

[robmarkallen]

@snowapeproductions aside from the simple fact they were running cable discs, so no oil to boil

[charliewecker]

@snowapeproductions Actually the rotor being bolted down will keep it from becoming warped, not to mention all the distribution holes. And as far as the rotor becoming brittle after being quenched. Not to fear, steal has to be at least 1400° before you can make it brittle from quenching. Also I don't think you can get "caliper warpage" on a fucking bicycle unless you're traveling at the speed of light. Which in that case "caliper warpage" is expected. Oh and what oil? Those are cable brakes.

[jabbawockeezrock101]

nice i bet you now gotta go buy a new disc 

[YourFatClownAss]

You obviously brake too much.

[samburger077]

i'm gonna assume that he intended to replace the rotors after that ride, & that he wasn't stupid enough to poor cold water onto a hot disc brake rotor.

[hairlesscatlover]

umm have you ever heard of disc warping? well, you most likely have brittle, warped discs now. enjoy. *dumbass*

[nd4spd420]

6" rotor and air shocks for downhill? time to upgrade

[rcpro88]

@nd4spd420 i use a fox 160mm float for freeride...its better than a sping cuz u can put more percise amount of air in, for best preformance, just cuz u cant afford a air shox doesnt mean its bad...the 888 boxxers fox40's all have an air option

[cgs26]

@rcpro88 Only boxxers have an air option, all 888s and 40s are coil. That is because coil forks are plusher and more linear due to the tighter seals required in an air fork. Air is MUCH lighter though

[airsoftjunkie2]

hahaha! WARPED DISK :P

[xHAMFISTSx]

One thing that tells us is that you are shit at downhill to break that much.

[nickoli201]

spray them with wd40 b4 you go out next time ;-)

[DKF22]

the rotors are too small for DH man, you need 185mm's

[rcpro88]

@DKF22 or 200mm like me

[tt01dwifta]

it could crack

[xXRazorspeedXx]

You have to clean the brakes

[dumpywhite]

Great way to warp your rotors.

[2176565]

Can anyone tell me how to fix squeaky disk breaks?

[brandontheninjag]

@2176565 put Vaseline all over them. XD

[reptilyy]

не х** себе

[assphincter]

And this folks is how you warp your rotors.

[airsoftbastard666]

wow shit how long did you brake for it to steam like that

[TheVampyreCat]

I've never had that happen, I've had my brakes get hot, but not that hot. Say goodbye to your brakepads.

[dd7root]

OP here. If you can ever have the cash, try the Italian Alps. For those that have bothered to read this far, I will reveal that those Kona Kikapus lasted about 7 descents, midway the last descent, both front and back brake pads were GONE on the other rig. Switched the pads from another one to the front just to make it down safely. Water was just extra at the end :)

[TaiiLuder]

Its not cool to have steaming hot rotors, Get off the brakes!

[civic4racing]

@TaiiLuder Lol get off the brakes have you ever seen downhill if you dont use your brakes you will die

[TaiiLuder]

I ride downhill my self, but i dont ride the brakes all the way down.

[gxz100]

ok, nice! now you have to buy new brakes!

[freediverga]

Dumbass +100

[evilamish]

This is why I would never buy used rotors

[dirtjumper024]

dumbass

[dalejrfan800]

Hey... that's cool and all. But when metal is cooled rapidly it does something called warping. Idiot.

[JokerPokerUberSmoker]

lol i bought a bike with wraped discs, and got it somewhat straight by bending them a bit hehehe, that guy will not be able to use them after that but he can straighten them... but thats a pain in the ass... it took me over fucking 3 hours to straighten one disc... thank god only one of them was wraped lol xD

[JokerPokerUberSmoker]

*warped, dubble spell fail :P

[antony1103]

@dalejrfan800 No its all good, they are not nearly hot enough at warp.

[poisonforlunch]

@dalejrfan800 thermal shock causes minute cracks in the material.

[dalejrfan800]

@poisonforlunch Which is... what? Deformation?(Sarcasm).

[Dementor0007]

I think it's normal...just when they change the color (from silver to blue-red-yellow-whatever) it gets dangerous...

and by the way it's not good for the disc when it gets cold in a short time...

ok sry i know...i'm a fool...and it looks nice to see the steam...

[mtnbikecrazy55]

Can you say warped rotors? Lol

[fskevin]

blue is 280°C ;-)

[LonelyXwalk]

Wow!!! I had burn my hand before n tat's sucks... =='

[frankster262]

wow those are really hot and i would buy new ones... but it is kind of cool to see it do that >.>

[MrTheWiCkED]

Bravi Bravi.. poi quando si spaccano comprate gli altri !

[pb4evr]

u just warped them

[TristianTV]

Yea thats smart pouring water on your hubs

[Allanlyngbye]

I don't wanna diss you equipment, but I wouldn't wanna be going fast enough, with those brakes and forks, to make them that hot.

[cerwinvegafan]

i see your both running the shittiest marzocchi fork ever made mz comps are horrible they came stock on my 05 specialized hardrock

[escorpion1991]

hahhah that was a very stupid you guys, you don´t know too much about physics, don´t you? :P...

[91slownotch]

they must like it when they wobble :)

[dko687]

well at least they can get some decent brakes after theyve broken these

[4StringRapist]

thats really bad for the discs.

[jakex4]

i warped mine =[

[1980gm9]

Can anyone say "rotor warp" :)

[Biscuitto]

LOL I ended up saying rope or wart

[flatfender1947]

I was waiting for the pop, "shit"

[billkar04]

nice gloves! μπραβο μαλακα!!!!

[NorthEasternSnow]

bad idea. the cold water will ruin your hot breaks. it may cause it to bend and become brittle

[olliewest]

Yea shock cooling is bad.

[rcpro88]

@NorthEasternSnow just about to type that

[14DylanC]

@NorthEasternSnow could warp them to if your planning on riding after doing that

[endrachwer]

@NorthEasternSnow it's a part of biking.. my friend just (two hours ago) smashed his pike with a 30kg rock and broke the hole shit! he acualy trew it like 5 times... freaking good fork...

[jdmk20aek]

@NorthEasternSnow this lol

[scubadiver75]

what do you expect from morons with reflectors in their wheels? lol

[DoubleDizzle1]

Marone!

[1887Nico1896]

Idiot... Water "fucks" your disc... Congratulations :-D

[AmegoProductions]

@1887Nico1896 i think he knew that while doing this lol

[endrachwer]

@1887Nico1896 it's a part of biking.. my friend just (two hours ago) smashed his pike with a 30kg rock and broke the hole shit! he acualy trew it like 5 times... freaking good fork...

[TheBiblemen]

@1887Nico1896 idiot.. its not called a disc but a rotor, and if ur riding in the rain ur brakes are gonna brake?

[terroridanny]

HAHAHAHAHAHAH... you screwed your disc

[booyahdex]

never EVER put water on hot discs.

[KIDLATBUHAWI]

stupid video. dont waste water . LOL

[Lukeriddoch]

DONT PUT WATER ON HOT DISKS.

Firstly you can make them very brittle if you do that so they will shatter if you hit a rock.

Also it can cause them to warp making them bend so you will have to true them (which will be risky as they may have become brittle) so leave them to cool down naturaly or you will have to pay £100 for new ones lol.

[biohazard1243]

those are avid bb5 and the disc brakes are about 5 bucks for the front and rear on ebay. i say put the water on. and they are made of a steel carbonate that already makes it brittle, they break if they hit a rock anyway.

[lloydc199207]

"Lukeriddoch" - A standard disc rotor without calliper isn't £100. A Hope Mono or Tech M4 rotor can be brought in the sought after 'saw' design in any rotor size (140,160,180,210) for £35. Avid Disc Rotors can be brought for a mere £18.99 on ebay or around £20 at your l.b.s.

Brake discs don't warp due to sudden contact with water, whilst hot, if not used straight after contact. (if done with heat cycle)

Please do not comment on a matter you dont understand

[suomirakion]

lol... ootteko suamalaisii..? :D

[dd7root]

Jep! Suomalaiset Italian alpeilla tekemässä empiirisiä kokeita puhkiajetuilla mekaanisilla levyjarruilla vuonna 2006.

[suomirakion]

ookoo :)

[harveyib114]

hey dummy you will damage the disc.(warp them)

[irishdrifter2k9]

i did this and they wernt as hot and i got my friend to touch dem XD

[brraatt]

we'll see how much they laugh when they notice that iots gonna cst them around 100 bucks to get new rotors to replace the rotors that were WARPED BECAUSE YOU PUT WATER OIN THEM, theyre not wotrth much anyways, hayes stroker ryde

[brraatt]

i meant like mx4 or somehing NOT STRKER RYDE

[EMM200]

so would it matter if they got wet because or rain?

[exchronicalcoholic]

rain wouldnt affect them, but definitely avoid the water crossing at the bottom of the hill until they have cooled enough to touch.

[ImDino]

19 seconds of a funny moment like this costs about 100 dollars...

[vpsshore]

You will definitely warp the rotors doing this but hey then again who cares, they are only shitty mechanical discs anyways! bahahaha

[celtic13dandamc]

dont waste the san pellegrino !

[Sanyey]

that was "pálinka" :DDDDD

[minimunGravity]

thats great thing to do if u want to brake your disc,not smart

[simplename92]

never do that rapid changes in temp will mess anything up!

[mateivornicu]

rapidly cooling metal makes it brittle - not the way you wanna have your breaks

[masso172]

Goood Job... NOOBS

[SanMiguel17Ekclan]

bremsen können verziehn und schief werden

[mockys2007]

blacksmiths on the loose..

[datki157]

what a dumbass, ever heard of warping?

[Linkinparklova177]

dude NEVER put water on ur bike
