  • how often would u say this needs to be done, plz reply

  • this doesn't help me at all...

  • do you have to take off the reservoir cap while bleeding the front brake?

  • Hello, I just flushed both brakes exactly as you did and bled them. Here's my question, when you pump the brakes and open up the bleed screw, should the pedal lose it's firmness? And yes, I tightened the bleed screw back. I think I need to change the brake pads too, as I honestly don't notice a whole lot of difference.

  • Alright thanks man that helped alot.

  • Alright so that would be reverse bleeding the brakes right?

  • @buddydog166 Yes. By pushing the fluid in from the bottom it forces the air up through the line and out of the master cylinder. It may still take a few minutes of bleeding to get the brake lever firm.

  • My brakes worked fine untill I took out the part of the brake cable that goes in the master cylinder, a bunch of brake fluid came out and I put it back in and the brakes didn't work. So I bleeded the brakes and it still doesn't work

  • @buddydog166 Ok, that makes sense, When you took the brake line off you got a lot of air into the system. Once this happens it's really hard to get it out. Your best bet at this point would be to open the bleeder on the caliper and drain all the fluid out. From there use a large syringe like in the video and slowly force fluid in through the bleeder until the master cylinder is full. Now you should have a little feel at the lever and should be able to bleed the brakes. Hope this helps!

  • Help my breaks won't bleed and when I pull in the front break lever the brakes don't grab. And I tried putting brake fluid in and bleeding it constantly

  • @buddydog166

    If you are doing everything correctly and the brakes still don't work your master cylinder is probably worn out. You can buy a rebuild kit and rebuild it. It's fairly simple to do but once you have installed the kit you will have to reverse bleed it like I show in the video in order to get all the air out.

  • No but it's best to leave it off while you are bleeding the brakes so you can keep an eye on the fluid level. Once you have the brakes bled with a good firm pedal or lever put the reservior cap back on and you are good to go.

  • does it matter if i put the master cylinder cover on before pumping the brake?

  • great, i have just realized that my disks on my aprilia sr have been boiling...they hav been sticking bad for ages! it was only till i stoped using the front brake that i noticed the rear sticking aswell so i sort of knew then it was me being so cool that ive been boiling my fluid..nice. i think i know wat to do now. can i do it without a syringe?

    i want to just pump all the fluid out then fill from top and drain it all through a bit. that will do right?

  • now i know why my brake dont work so well ill look it up on this usefull place called youtube!!!! lol

  • thank you sooo much this was very helpful

  • wouldnt you get air in the front master cylinder if you left the bleeder screw open??? how does it just flow out of the front and not the rear? is it because the front line is vertical?

  • Very helpfull thankyou

  • many thanks from sweden : ) help me alot!

  • DUDE!!!!!! you are the man!!!!!!! That worked so awesome!!!! Iv'e been doing brakes on cars for years and for what ever reason that's the forst time I have heard of reverse bleeding.......soooo cool and so fricken simple.....ne neeed for bench bleeding or anything.....I got a syringe from my feed store thats for horses and has a continuous pressure....it worked like a charm...thatnks thanks thanks.....you saves me a hundred miles of driving and hours of frustration.....not to mention shop hours

  • Awesome!!!! Thanks for the info!

  • Can I reverse bleed my front brakes? I have a 05 crf 450 r and the front brake line broke. I replaced it and I cant get any fluid to go from the master cylinder to the caliper. I hold my finger over the hole where the banjo bolt goes and I get a little pressure .....but it does not flow freely to the caliper....so agian...can I reverse bleed the front brakes....it makes sense...I like the rubber hose and shryinge thingy.....cool video...

    joe Nor CAl

    thanks

  • @jdgarwood66

    Yes, reverse bleeding works on both the front and rear brakes. Just remember to force the fluid through very slowly to push as much of the air out as possible.

  • @ForsheeMS does it matter if u use a differant brand brake fluid than whats in the brake system

  • @emoskater1212

    No, the brand of fluid doesn't matter as long as it's DOT 3 or 4 compatible. I prefer the Valvoline synthetic Dot 3 or 4 brake fluid as it has a high boiling point and tends to work very well.

  • so it's, with the bleeder screw open, pump the brakes, then close the bleeder screw before you stop???

  • @twistedkeys1

    Yes. Absolutely do not let up off of the lever until the bleeder screw is closed or it will suck air back into the system.

  • @ForsheeMS Good to know thanks dude! I'm def subbing!

  • What kind of grips are those. By the way great video it helped me out a lot.

  • @ktmlover200

    Pro Taper Pillow Top grips.

  • @ForsheeMS Great video, thanks. I've never done the brakes on my bike but I will before my season starts.

  • I got new brake pads, but they are to thick to fit into the capilar. I not sure what to do. i am either going to open the bleeder screw or remove the capilar. What do you recomend?

  • @NomaDairy

    Use a large flat blade screwdriver to gently push the piston into the caliper. once you've done that the new pads should slide right in.

  • thanks for the video. but i have a problem with my front brakes if i hold them on for to long (10 sec) they screach and i have replaced the pads about 1 month ago. PLEASE REPLY. Thanks

  • @ElliotScoots14

    Sounds like the slider pins are either worn or sticking. The caliper slides side to side on 2 pins. Sometimes they will rust up and get sticky and need to be cleaned and lubed. Occasionally they wear to the point they have to be replaced. Check that out and see what you find.

  • @ForsheeMS i will thanks for your help.

  • This video was really usefull !!! keep up the good work!!!

  • Good video man.. Keep up the good work! Very informative

  • My front brake on my 2006 Rmz-250 only work for a split second... when im out on the track i can grab the front brake and it will bite for about 4 feet then it will lose pressure and be useless but once i let the brake lever go it will work the same way again...i belive this was caused due to me droping the bike off the stand and the lever being force pushed all the way in... but when i checked the caps on my master cylinder they looked fine.... what could be my problem?!?!?!?!?! PLEASE RESPOND

  • @StoneMXfan369

    Sounds like you need to rebuild the master cylinder. Most likely one of the seals is damaged. It probably happened when the bike fell off the stand. You can try bleeding the brakes first to make sure there is no air in the system but if that doesn't work you will need a rebuild kit. Good news is a kit is fairly cheap and easy to install as long as you have a pair of internal snap ring pliers.

  • @ForsheeMS thanks... ya i checked the piston today and one of the seals on it was torn so whe just ordered the new piston... and your video is really gunna help us bleed the brake once we get new fluid in it THANKS!!

  • Thanks, really clear, helpful guide. I was riding along the street the other day when my front brake suddenly applied itself and locked up! Chucking me down the street...Ive cleaned them all up, and now trying to bleed them, but want to know what could cause that so it doesnt happen again! Any ideas? (Its a KTM 450 EXC) thanks!

  • @0to60tv

    Take a close look at the pads to see if they are wearing evenly. If they are wearing at an angle you probably have a slider pin that's rusted. When the pads wear on an angle they can "grab" the rotor and lock the wheel up. If this is the case you will need to fix the pin and replace the pads. Let me know what you find.

  • Hi, Great video and very informative. I do know how to bleed brakes but wanted to know what is your method for finding air leaks? My son lost his brakes in a race on his 07 yz250 after 1st lap...bled them out and sent him back out and then he lost them again at 3rd lap. Pads brand new. One of my friends said it could be the two brass washers that go from the brake line into the caliper. Any info on finding a leak would be great. Thanks again for all your help! Ann NETRA 262

  • @enduroryda Because the brakes create far more pressure than vacuum normally any leak at all will result in a visible fluid leak instead of pulling air into the system. From what you have described it sounds more like the master cylinder. A master cylinder rebuild kit would most likely solve your problem.

  • @ForsheeMS Thanks for your reply! I have rebled them and they are nice and solid feeling. I'll keep my eye out for leaking fluid and let you know how I make out once we get a practice ride in. Did get a bit more air out and slightly depressing the foot lever as I cracked the bleeder screw helped push those through. Thanks again.

  • @enduroryda

    Could be warped rotors that are pushing the brake pistons back in, resulting in no brake pressure

  • is there any other reason for the tube other than catching the fluid? because i couldnt find a tube in my garage and i wanted to flush the fluid in my yz250 without it and the brake seems to pull in too far.. "The lever i mean" I'm looking to make the the front brake nice and firm...

  • @JuicyFruitFresh

    It's not 100% neccessary but it does make the job a lot cleaner as you don't have brake fluid running everywhere. The other advantage is that you can see the air bubbles coming out of the caliper. So to answer your question, yes, you can do it without the tubing but you are going to have a mess to clean up.

  • hey, ive tryed bleeding my front brake on cr250, when i close the bleed nipple off, the fluid still goes back into the nipple/caliper, is my system broke????

    reply as soon as you can please, daz UK

  • @shabow1987

    Ok, are you using clear tubing similar to what I used in the video? If so what you might be seeing is the fluid is actually draining out of the tubing into your catch container. If you watch it really close you should see that it's not going back into the bleeder screw although that's what it looks like. If the bleeder nipple was leaking that bad it should squirt brake fluid each time you pulled the brake lever and you would have no brakes at all. Let me know what you find.

  • @ForsheeMS your totally right!!!!!!!! the brake is sorted thanks to you cheers forshee!!!! A+++

  • i have a completely dry front brakes at the moment, how do i go about putting fluid in? do i just reverse bleed with the syringe first like you did with the rear?

  • @swk138

    Yes, reverse bleed with a syringe. Be sure to use a large enough syringe to completely fill the system and pump it in very, very slowly. When done right it shouldn't take long at all to get all the air out.

  • cheers mate, you just saved me some money. nice film.

  • hey i have a question when i sqeeze my front brake it doesnt feel solid it feels loose and doesnt stop my bike when i brake only sometimes. i tryed the whole bleeding thing for about 10 mins and still dont have it solid when i squeeze it still loose i dnt know if my master cylinder is messed up or if im doing something wrong. plz help thanks.

  • @rdizzle0042

    Sometimes I have bled the brakes for 30 minutes before they were good. It can take a lot of work to get all the air out which will cause a spongy feel in the brakes. The reverse bleed method helps push most of the air out.

    On the other hand, a bad master cylinder will cause a very spongy feeling brake. If you are fairly confident that the master cylinder is the problem you could purchase a rebuild kit and rebuild it. Hope this helps.

  • @ForsheeMS ok thanks do u know how much the rebuild kit cost i kinda looked into it was like 40 bucks does that sound right i have a 04 kx 125.

  • @rdizzle0042

    I have bought them for around $25 but it was an aftermarket kit. Can't remember the brand. When you rebuild it make sure the bore of the master cylinder is smooth with no burrs. if needed you can use some 800 to 1000 grit sandpaper to clean up the bore a little but be sure to flush it out really good.

  • Worked great did it by myself on my crf230 A+++++

    Thanks

  • Very Nice Video

  • I did everything you did, and still, no luck! After I bled the rear brakes like in the first video, there was absolutely no pressure when I pressed on the lever. I'm guessing it's air, lol. Also I can't find a huge syringe, lol, would CVS have them? Thanks

  • i cant figure out how to bleed the rear brakes on my 02 yz 125. i did everything like you said to do exept i didnt reverse bleed it and i didnt have a tube on the caliper nipple. i pumped the brakes and opened the bleeder screw and i held the brake down and air just kept coming out. and i made sure the brake fluid was topped off

  • @joshwaggoner14

    Sounds like you still have a lot of air in the system. Sometimes I have bled brakes for 30 minutes or more before getting all the air out. Keep bleeding them and it should start getting better.

  • Hey forshee,, have you ever seen brake fluid turn to like a sticky jelly substance?

    I just bought a used ktm 380 and I have never seen this before. Its like rubber cement but stickier,.

    I am woried about the whole system now.

    The only place we checked was the resevoir for the back break, nowhere else yet, ran out of time.

    Appreciate the video, good refresher

  • No, I have never seen anything like that. I guess it's possible that someone mixed different fluids like a DOT 4 and a DOT 5 together but I still don't think those would jell up when mixed. Unfortunately your best bet would be to completely rebuild the entire system to avoid problems down the road.

  • I was afraid of that. Got a coos bay dunes trip next week too.

    Thanks for the response

  • when bleediing the brakes do u need to pump the pedal to get all the fluid out or will it just drain 4:09

  • On the rear brakes you will have to pump the pedal. The front will drain by just opening the bleeder screw.

  • thanks bro, I know it's a simple task, but it always helps to have a vid to refer too.

    Nice bike by the way!

  • Great video demo. What kink of fluid do you recommend?

  • Valvoline synthetic dot 3 or 4. Check out part 1 of the video, I talk about it there.
