How Disc brakes work - Pro/E animation

Hi.. this is Srikrishna.A.S from Chennai

This is a kinematic animation of a floating caliper disc brake done in Pro/Engineer Wildfire 2.0 by me.

It won the first place in the SAE - ( Society of Automobile Engineers ) tier - II Design and animation competition.

Good Effort Krishna. 1 doubt though :: I see that the brake pad is displacing the wheel from it's plane of rotation ~(0:10). Is that right? (This may be clearer if seen in slow motion.)

@sakivg25 At 00:10 The brake pad is not displacing the Brake rotor. Instead, it is the caliper sliding on the two pins.

Initially, the hydraulic pressure moves the inner side brake pad to contact the rotor. After this happens, newton's third law of equal and opposite reaction takes over and causes the outer pad to be pulled in towards the rotor till it also makes contact. The sliding caliper design is meant to facilitate this motion.

tell me why there are perforations in the disc.... random holes...? are they random at all???

[intellofreak]

@srikanth94 They are not random holes. They are there to aid better dissipation of heat and fumes away from the braking area as the pads press against the rotor. The thin long recesses are for shaving off the surface of the brake pads ever so slightly to prevent "glazing" (Glazing is the phenomenon where the brake pad takes on a glassy, smooth appearance because of the fusion caused by the heat from the braking) and to ensure maximum brake bite (stopping power).

this is a pretty cool animation man but the thing is, it doesn't really show how the disc brake works, I dunno maybe do the same with the calliper transparent or something?, if you would have done this, I woulda given you 5*, but 4 for now

[intellofreak]

Glad that you noticed it !!

[AhmadAboulFarag]

Is there a program for simulation of generated heat, and friction?

[gabriell16bishop]

that explained nothing. maybe if you made some parts transparent so we could see what was happening.

I would never draw on Pro E again. I did a beginner's lesson and I still required help.

[emachines34]

Very impressive, I am trying to make this in Solidworks. I was hoping if you could kindly tell me what materials you used for

a) the brake discs

b) the brake pads

c) the calliper

@srikanth94 rotors have slots and drilled holes to dissipate gases and brake dust witch can lead to brake fade
