How the Brake System Works In a Car
Master Cylinder
 Located in front of driver
 Consists of a piston in a sealed bore
 Mechanical force input, hydraulic
force output
Failure and Problems Encountered
 Caliper
 Located at each
wheel
 Similar to Master
cylinder
 Hydraulic input
force, mechanical
output force
 Rotor and Brake Pads
Rotor
 Located at each wheel
 Iron with highly machined surface
Brake Pads and Brake Shoes
 Rubs against rotor
 Metal with high friction lining
 The difference
Types of Brakes
 Forces Generated by Brakes
The Brake Pedal
Caliper
Applying Brakes Forcefully
 Forces
 Equilibrium
 Wheel Lock
Forces & Equilibrium
 A car in constant motion has forces that are balancing one another (equilibrium)
 Forceful application of brakes causes the forces to be out of balance
 Consequences of Wheel Lock
Front Bias
 Increased front rotor diameter
 Increased front brake pad coefficient of friction
 Increased front caliper piston diameter
Wheel Lock in a front bias car
Imbalanced forces (rear wheels)
 Role of Fluids in Brake System
 Role of Fluids in a Brake System
 Easily transfers force to each wheel
 No need for complicated system of
rods and pulleys
 Essential to magnify force
 Pascal’s principle: hydraulic lift
Conclusion
Components of brake System
 Master cylinder
 Caliper
 Rotor and Brake Pads
Forces
 Mechanical force, hydraulic force, friction, torque
 Equilibrium
 Wheel lock
Fluids
 Transfer forces
 Magnify forces
