CDX CH. 35 Disc Brakes

Removing the rotor is usually required when the rotor:

• is under the specified minimum thickness.

• would be under the minimum thickness after machining.

• Both A and B

• None of the above

True or False. Rotors that are too thin cannot handle as much heat and will experience brake fade.

• True

• False

Once all of the lug nuts have been torqued, go around them again, this time in a ​_______ to ensure that you did not miss any in the previous pattern.​

• Circular pattern

• Star pattern

• Alternating pattern

Brake diagnosis usually starts with understanding the customer's:

• position.

• concern.

• own diagnosis.

• cause.

On some vehicles, disc brakes are equipped with a steel scratcher that:

• allows the technician to know if the brakes need adjusting.

• makes a noise if the wheels come too close to a curb.

• makes a noise if the brake pads are due to be replaced.

• leaves a tell-tale mark on the rotor if it is warped.

Under tightening the lug nuts can lead to ________.

• The wheel studs breaking immediately

• The wheel studs breaking after the vehicle has been driven for a period of time

• Loosening of the lug nuts and result in the wheel working its way off the vehicle

• Both A and B

Brake dust is best removed from brake components on the vehicle by using:

• compressed air.

• brake solvent.

• a damp rag.

• a brake wash station.

Excessive brake disc rotor thickness variation will cause:

• steering wheel shimmy.

• a brake surging feeling.

• Both A and B

• None of the above

All of the following can cause brake system dragging, EXCEPT:

• stuck caliper piston.

• misadjusted master cylinder pushrod length.

• restricted brake line or hose.

• internal master cylinder leak.

Technician A states that brake rotors can be refinished on or off the vehicle. Technician B states that brake drums can be refinished on and off the vehicle. Who is correct?

• Tech A

• Tech B
