Title: Automotive Brake System


1
Automotive Brake System
  • The Basics

2
What stops it?
  • Friction
  • Kinetic friction
  • Creates heat
  • Heat is brakes worst enemy
  • Weight transfers to front
  • 70 braking performed by front brakes

3
Applying the friction
  • Disc brakes will use pads to squeeze the rotor
  • Drum brakes use shoes to press outwards against
    drum

4
Lining material
  • Non-metallic
  • Made from synthetic fibers (used to be asbestos)
  • Semi-metallic
  • Made from iron and synthetic fibers
  • More fade resistant - harder pad
  • More prone to squealing
  • Full-metallic
  • Made from sintered metals
  • Very hard pad

5
Hydraulics - its how the pressure is multiplied
and transferred
6
Hydraulic pressure is distributed equally in all
directions
7
Same line pressure to all wheels
8
The pressure that is applied at piston A is the
same as what is applied to piston B
9
The hydraulic pressure is the same, but the
applied force can be changed by changing the
piston size.
10
The area of the piston is determined by using the
formula
  • 3.14 X R2

11
The amount force is calculated by multiplying the
pressure times the area
  • P X A Force

12
You cant have something for nothing
13
The caliper piston needs more applied force for
multiple reasons
