Braking system - operation principle

MA project - The chosen issues of modeling and visualization of car.
Sorry for subs in Polish, but they are added in Adobe Premiere and as a result integrated in movie file. Changing it requires rendering Premiere project again (which requires some time) :/ Instead I put some annotations in English :) Hope they will help

why is the rear brake disc only slotted and not cross-drilled?

[Thomson1024]

@jianh1989 Rear brakes don't have to stand as massive forces and heat as those in front. So rear discs are smaller and don't need to be slotted and cross-drilled, one of these features is usually enough to dispose heat.

@Thomson1024 I see, but how does cross-drilled or slotted design can help a disc brake disperse heat?

[Thomson1024]

@jianh1989 Slots and holes increase the disc's overall area that contacts with flowing air. The bigger the area, the more heat can be dispersed. It also helps when disc gets really hot - it deforms less when it expands (that's for steel discs, ceramic and carbon don't expand and deform much because of heat, I suppose). I decided to create such set of discs for this car because it is a concept of a supercar - so it goes fast and has to brake efficiently :)

@Thomson1024 also for stability purposes the rear discs have to be less powerful, cuz all the braking systems are more or less combi brakes and if the rearbrakes hit hard then the car gets displaced sideways.

[Thomson1024]

@INSAnityIz That's right. Usually fluid pressure is lower in rear calipers (that means the overall brake balance is moved towards front) and discs are smaller, because they don't need to stand such big forces as the front ones.

This(the video,music) is so CooL;) & after many a hundred YOUTUBE watch a day (not quite literally...though!) a very healthy synergy above. One GEM of a Kind.pranaAm

doubt is clear.. and mind blowing graphics... All scaling, translating, Rotating and transposing... perfect...

@Thomson1024 Thanks =)
