Exam 52: Disc Brakes

Which of the following statements concerning brakes is NOT correct?

Disc brake caliper pistons are being removed. Technician A positions a large dull screwdriver in the piston's dust boot groove to pry out the piston. Technician B injects 25 psi (172 kPa) of air pressure into the fluid line connection bore to remove the caliper piston. Who is correct?

Name four major advantages of disc brakes as compared to drum brakes.

Technician A uses compressed air at 150 psi to remove the piston from the caliper bore. Technician B uses special internal expanding pliers to remove pistons from caliper bores. Who is correct?

Technician A siphons out about two-thirds of the brake fluid from the master cylinder reservoir before beginning work on the pads or calipers. Technician B opens the caliper bleeder screws and runs a hose to a container to catch the fluid that is expelled,.while pushing the pistons back. Who is correct?

Technician A says some caliper designs use only one pad lining per brake assembly. Technician B says some disc brake pads have wear sensors. Who is correct?

Which of the following is NOT associated with a pedal pulsation problem?

In most calipers, the dust boot is installed in the caliper bore groove before the piston is installed.

Disc brakes require more force than drum brakes to achieve the same braking effort.

Disc brake rotor conditions are being discussed. Technician A resurfaces the rotor if it has lateral runout, lacks parallelism, or is scored. Technician B resurfaces both the left and right rotors even if only one rotor has problems. Who is correct?

A fixed caliper _____.

Rubber insulators and caliper pins should be lubricated with ____________________ dielectric compound

The inner and outer races of tapered roller bearings are ____________________ shaped.

A dust boot seal automatically adjusts caliper piston position.

Uneven lug nut torque can cause a pulsating brake pedal.

____________________ caliper disc brakes slide back and forth on pins or bolts.

All manufacturers recommend honing the caliper bore when overhauling the calipers.

Caliper housings are made from ______.

What nonbrake component concerns can cause the vehicle to pull when the brakes are applied?

A ____________________ type caliper has angular machined surfaces at each end that slide in mating machined surfaces on the anchor plate. This is where the caliper slides back and forth.
