TIONS AND VERIFIED ANSWERS|GRADED A+|PASS FIRST AT-
Warped brake rotors - ANSWER A likely cause of the brake pedal slowly going to the floor
when normal braking pressure is applied.
Contaminated brake fluid - ANSWER A possible reason for the brake pedal slowly going to
the floor under normal braking pressure.
Internal leak in the master cylinder - ANSWER A common cause for the brake pedal going
to the floor when normal braking pressure is applied.
Faulty brake booster - ANSWER A potential issue that could cause the brake pedal to
slowly go to the floor during a road test.
Vacuum power brake booster test - ANSWER To test it, disconnect the vacuum hose and
observe engine idle.
Brake pedal pumping test - ANSWER Pump the brake pedal at least 4 times, hold the
brake pedal depressed, and start the engine to test the vacuum power brake booster.
Parking brake application - ANSWER Apply the parking brake and start the engine as part
of the vacuum power brake booster test.
Vacuum check at the booster - ANSWER Check for vacuum at the booster with a gauge to
test the vacuum power brake booster.

, Disconnecting the ABS fuse - ANSWER A method to depressurize an ABS system.
Pumping the brake pedal - ANSWER Pump the brake pedal at least 25 times with the igni-
tion off to depressurize an ABS system.
ABS self-diagnostic test - ANSWER Running this test is one way to depressurize an ABS
system.
Dragging rear brakes - ANSWER The most likely cause after new linings installed and
drums machined is a stuck parking brake cable.
Warped drums - ANSWER A possible reason for rear brakes dragging after new linings are
installed.
Improperly adjusted brake shoes - ANSWER A likely cause of rear brakes dragging after
new linings and machined drums.
Leaking wheel cylinder - ANSWER A likely cause for low brake fluid levels observed during
inspection.
Faulty master cylinder - ANSWER Another possible cause for low brake fluid levels during
inspection.
Air in the brake lines - ANSWER A potential reason for low brake fluid levels observed by
a technician.
Warped brake rotors - ANSWER A condition where the brake rotors are not flat, causing
uneven braking.
