Warped brake rotors A likely cause of the brake pedal slowly going to the
floor when normal braking pressure is applied.
Contaminated brake fluid A possible reason for the brake pedal slowly going
to the floor under normal braking pressure.
, Internal leak in the master cylinder A common cause for the brake pedal going to the
floor when normal braking pressure is applied.
Faulty brake booster A potential issue that could cause the brake pedal to
slowly go to the floor during a road test.
Vacuum power brake booster test To test it, disconnect the vacuum hose and observe
engine idle.
Brake pedal pumping test 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 Apply the parking brake and start the engine as part
of the vacuum power brake booster test.
Vacuum check at the booster Check for vacuum at the booster with a gauge to test
the vacuum power brake booster.
Depressurizing an ABS system The proper way includes opening the bleeder valves.
Disconnecting the ABS fuse A method to depressurize an ABS system.
Pumping the brake pedal Pump the brake pedal at least 25 times with the
ignition off to depressurize an ABS system.
ABS self-diagnostic test Running this test is one way to depressurize an ABS
system.
Dragging rear brakes The most likely cause after new linings installed and
drums machined is a stuck parking brake cable.
Warped drums A possible reason for rear brakes dragging after new
linings are installed.
Improperly adjusted brake shoes A likely cause of rear brakes dragging after new
linings and machined drums.
