Automotive Service Excellence (ASE) - Brake System Test
with complete solution(2023)
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 (ABS)
What are disc brakes?
brakes that use a pair of friction 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 the rotors when the brakes are applied
, What are rotors?
discs that are either solid or vented and which cause the vehicle to stop based 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 when the 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 wheel cylinders?
to push the shoes out against the drums
