1. Brake drum machined beyond its limit: Which of the following conditions can
cause brake fade?
a. Seized wheel cylinder piston
b. Brake drum machined beyond its limit
c. Leakage past the master cylinder cups
d. Air in the hydraulic system
2. Neither Technician A nor B: With the brakes applied on a vehicle with power
brakes, the pedal moves down slightly when the engine is started.
