Multiple Choice

On a car with disc/drum brakes, the front brakes grab quickly when light pedal pressure is applied. This problem could be cause by a bad:

• Proportioning valve

• Pressure safety valve

• Metering valve

• Residual check valve

Multiple Choice

The driver of a vehicle with power disc/drum brakes says the brake pedal moves slowly to the floor while maintaining pedal pressure at a stoplight. What could cause this problem?

• Leaking primary piston cup in master cylinder

• Leaking power brake booster

• Leaking residual check valve in master cylinder

• Internal leak in the combination valve

Multiple Choice

On a vehicle with single piston floating caliper front disc brakes, the brake pads on the left side on the vehicle are almost completely worn while the right side is almost new. Technician A says that too much rotor runout could be the cause. Technician B says that a binding caliper piston could be the cause. Who is right?

• Technician A only

• Technician B only

• Both A and B

• Neither A nor B

Multiple Choice

A hydraulic brake line is leaking. Which of the following is the correct repair procedure?

• Cut out the bad section and replace with single-flared steel tubing using flare nuts and unions

• Replace the leaking line with double-flared steel tubing

Multiple Choice

With foot pressure applied, the brake pedal on a vehicle with vacuum assisted power brakes moves down slightly when the engine is started. Technician A says this condition can be caused by a leaking power brake booster diaphragm. Technician B says the cause could be a faulty power brake booster check valve. Who is right?

• Technician A only

• Technician B only

• Both A and B

• Neither A nor B
