Regulate pressure applied to brakes
Measure brake fluid levels
Generate braking torque
Phenomenon that causes hydraulic fluid to vapourise at high temperatures leading to brake failures
Vapour lock
Brake fade
Cavitation
Fluid boiling point
Type of brake fluid generally considered hygroscopic, meaning it absorbs moisture from air
Dot 3
Silocon based
Dot 5
Mineral oil based
Hydraulic advantage in brake systems is typically created by ratio of
Wheel to piston size
Piston size in master and slave cylinders
Pedal travel to fluid displacement
Pedal force to master cylinder displacement
Primarily responsible for returning brake pads to original position after braking
Caliper
Return Springs
Brake rotor
Brake piston
Role of brake booster in hydraulic brake system is to
Enhance hydraulic pressure
Increase mechanical force by driver
Cool down brake fluid during operation
Maintain fluid levels in master cylinder
Problems with using wrong type of brake fluid
Excessive braking power
Corrosion of brake system components
Brake fluid becomes incompressible
Need for frequent brake maintainance
