Unit 3: Braking System - Activity 2: Disc Brakes

What is one advantage of using disc brakes over drum brakes?

• Disc brakes dissipate heat more effectively than drum brakes.

• Drum brakes are self adjusting.

• Drum brakes are easier to service.

• Drum brakes are less prone to brake fade.

Disc brakes are self adjusting. As the brake pad wears, the ______ moves out to compensate for the wear.

• piston

• caliper

• rotor

• brake line

Disc brakes are normally easier to ______.

• service

• install

• replace

• paint

Because of the ability to dissipate heat quickly, the disc brake is less prone to ______.

• brake fade

• corrosion

• oil leakage

• wheel misalignment

What is brake fade?

• When a brake assembly cannot dissipate heat quickly enough.

• When the brake pads are new.

• When the caliper is replaced.

• When the vehicle is parked.

• Outboard brake pad

• Steel plate

Refer to the picture showing a front disc brake assembly. What should flex lines be checked for?

• Cracks, splits and leaks

• Proper color coding

• Presence of metal fittings

What is the function of the friction material attached to the steel plate?

How is the friction material attached to the steel plate in a brake pad?
