D)Disc brakes are commonly used on the rear wheels

Answer 1

C

Question 2

A caliper that is mounted directly to the steering knuckle and has a piston on each side of the rotor is called a ........caliper.

Answer 2

C)Both A and B
D)Neither A nor B

Answer 3

C

Question 4

Clips and ........are commonly used to limit the noise generated by disc brakes.

Question 5

The ........seal around the caliper piston prevents fluid loss and acts as the piston return spring.

A)Technician A
B)Technician B
C)Both A and B
D)Neither A nor B

B)Sliding
C)Fixed
D)All of the above

Question 8

A rotor with a cast iron friction surface and a thin stamped steel hat is called a ........
rotor.

Question 9
