ASE brakes pr. 4

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

Which of the following would MOST LIKELY happen if the measurements taken from the check shown above varied from the manufacturer's specifications?

• Noisy brake operation

• Brake grab or pull

• Pulsating brake pedal

• Low brake pedal

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

• Cut out the bad section and replace with new steel tubing using compression fittings

• Replace the leaking line with double-flared, seamless copper tubing

• 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

The set-up shown above is used to check:

• Rotor parallelism

• Wheel bearing adjustment

• Rotor lateral runout

• Rotor face wear

A customer complains their vehicle pulls to the right when the brakes are applied. Technician A says a restricted brake line to the left caliper can cause this problem. Technician B says a malfunctioning proportioning valve is probably the cause. Who is right?

• Technician A only

• Technician B only

• Both A and B

• Neither A nor B

Technician A says the tool shown above is used to adjust the brake shoes. Technician B says the tool shown above is used to determine the inside diameter of the drum. Who is right?

• Technician A only

• Technician B only

• Both A and B

• Neither A nor B

All of the following could cause a hard brake pedal on a vehicle with power brakes EXCEPT:

• An engine with the valves adjusted too tight

• Brake fluid on the linings

• A leak in the brake hydraulic system

• A frozen caliper

Which of the following disc brake caliper designs usually allow the brake pads to be removed without removing the caliper?

• Fixed

• Floating

• Sliding

• All of the above

All of the following can cause disc brake squeal EXCEPT:

• Loose or missing anti-rattle springs

• Grease on the linings

• Glazed linings

• Dirt embedded in the linings

All of the following can cause a vehicle to pull to one side when the brakes are applied EXCEPT:
