Disc Brake System and Service

  All of the following statements about are true, EXCEPT:

• Disc brake pad and rotor service is similar for every kind of disc brake system.

• The most common disc brake problems are noise and hard pedal.

• Disc brakes commonly produce high pitched squeals or squeaks.

• Pulsation is usually caused by rotor problems.

Technician A says that observing pad thickness is a good way to determine pad condition. Technician B says that a grooved rotor is a sign of wheel bearing wear. Who is right?

• Tech A

• Tech B

• Both A & B

• Neither A or B

Pushing the pads away from the rotor makes ______ removal easier.

• Pad

• Caliper

• Rotor

• Dust Boot

Loaded calipers are new calipers with the _______ already installed.

• Pads

• Pins

• Rotor

• All of the above

All of the following statements about pushing the caliper piston into its bore are true, EXCEPT:

• Before pushing on the piston, loosen the bleeder screw.

• Push on the piston with a large C-clamp.

• Place a pan under the caliper to catch brake fluid.

• Tighten the bleeder only after the C-clamp is removed.

Do not allow any anti-squeal compound or lubricant to touch the ______.

• Pad friction surfaces

• Pad shoe

• Rotor

• Both Pad friction surface & Rotor

A rotor will not turn freely after the caliper is installed. Technician A says to drive the vehicle and apply the brakes a few times to loosen the rotor. Technician b says to loosen the wheel bearings until the rotor turns freely. Who is right?

• Tech A

• Tech B

• Both A & B

• Neither A or B

To check a rotor for runout, use a _____.

• Dial indicator

• Brake micrometer

• Feeler gauge

• Any of the above.

Technician A says that all bearing play should be removed from an integral rotor before runout is checked. Technician B says that a non-integral rotor should be bolted to the hub before the runout is checked. Who is right?

• Tech A

• Tech B

• Both A & B

• Neither A nor B

A brake lathe can be used to remove _____ from the rotor.

• Scoring

• Bluing

• High Spots
