Brake System Flashcards
What are the major components of the brake system?
disc brakes, brake pads, calipers, rotors, drum brakes, drums, shoes, drum hardware, wheel cylinders, master cylinder, pressure differential valve, proportioning valve, brake fluid, brake hoses and lines, anti-lock brake system
What are disc brakes?
brakes that use a pair of frictions pads to squeeze against a flat disc or rotor when the brakes are applied
What are brake pads?
The friction linings used with disc brake systems
What are calipers?
Parts that, in disc brake systems, are used to squeeze the brake pads against the rotors when brakes are applied
What is the purpose/function of calipers?
to squeeze the brake pads against rotors when the brakes are applied.
What are rotors?
discs that are either solid or vented and which cause the vehicle to stop on the friction between them and the brake pads
What are drum brakes?
a type of brake system that uses a cylindrical drum as the friction surface for a pair of brake shoes
What are shoes?
the friction linings inside a brake drum
What is the purpose/function of shoes?
to squeeze outward against the inside of the drum to apply the brakes.
What is drum hardware?
return springs, hold down springs, self-adjusters, cables, clips or springs
What is the purpose/function of return springs
to pull the shoes back away from the drum with brakes are released
What are wheel cylinders?
the hydraulic component inside a drum brake that pushes the shoes out against the drum, it has two opposing pistons that move outward when pressure is applied
What is the purpose/function of the wheel cylinders?
to push the shoes out against the drums
What is a master cylinder?
a component that applies hydraulic pressure to the calipers and wheel cylinders when the brakes are applied
What is the purpose/function of a master cylinder
to push fluid through the brakes lines to each wheel to apply the brakes (when the brake pedal is depressed)
