Accepted Answer

A) True 
 B)False  True

Question 9

Why should disc brake drag be avoided?

Accepted Answer

Brake drag increases pad and rotor wear and creates friction that the engine has to overcome, wasting fuel. Heat buildup in brakes will warp the rotors and drum, and may overheat the wheel bearing grease.
