A technician is measuring the inside diameter of a brake drum with a brake drum micrometer. The technician should use which of the following measurements.

Two technicians are discussing brake backing plates. Technician A says if a ridge has formed on the pads where the shoes rest they may be filed to restore a smooth finish. Technician B says to apply bearing grease to reduce brake squeak. Who is correct?

A vehicle has a low brake pedal. Technician A says an improperly adjusted brake pedal could be the cause. Technician B says overheated brake fluid could cause this condition. Who is correct?

A vehicle with power assisted brakes has a hard brake pedal. Which of the following is LEAST likely to cause this condition.

A vehicle pulls to the left only when the brakes are applied. This condition is MOST likely caused by:

Technician A says accumulators are found only on non-integral ABS systems. Technician B says some integral ABS units contain high pressure accumulators that must be discharged before repair. Who is correct?

Technician A says ABS control units are programmed to ignore speed sensor input variations below a certain threshold. Technician B says a one-channel ABS system controls hydraulic pressure to the rear brake units. Who is correct?

During a brake inspection one rotor is found to be much hotter than the other. Technician A says this could be caused by a sticking brake caliper. Technician B says this could be caused by the brake caliper piston seal. Who is correct?

Two technicians are discussing master cylinder residual check valves. Technician A says the check valve is used on four wheel disc brake systems. Technician B says the valve maintains pressure when the brakes are released. Who is correct?

It is noticed during a brake inspection of a front disc rear drum brake system that one shoe is worn more than the other. Technician A says that this is caused by a faulty residual check valve. Technician B says this is caused by a faulty proportioning valve. Who is correct?

A vehicle with ABS brakes has an audible clicking noise when it is first started. The noise goes away after a few seconds. Technician A says this is one of the hydraulic valves in the hydraulic valve assembly sticking. Technician B says this is a normal condition. Who is correct?
