Technician A uses a dial indicator to measure parallelism. Technician B uses a dial
indicator to measure runout. Who is correct? - Answer-Technician B only
Two technicians are discussing the reason that the brake fluid level in the master
cylinder drops. Technician A says that it may be normal due to the wear of the disc
brake pads. Technician B says that a low brake fluid level may indicate a hydraulic leak
somewhere in the system. Which technician is correct? - Answer-Both Technicians A
and B
After resurfacing a brake drum, Technician A cleans it using hot water and a lint-free
cloth, and then uses compressed air to thoroughly dry it. Technician B cleans the drum
using a lint-free cloth dipped in a special brake cleaning solution. Who is correct? -
Answer-Technician B only
A vibration or pulsation in the brake pedal when the brakes are applied is usually
caused by ______. - Answer-Warped rotors [runout]
Disc brake rotor conditions are being discussed. Technician A resurfaces the rotor if it
has lateral runout, lacks parallelism, or is scored. Technician B resurfaces both the left
and right rotors even if only one rotor has problems. Who is correct? - Answer-Both
