Pedal Falls Away

A brake pedal that falls away under steady foot pressure is generally the result of a system leak or fluid contamination. The leak point could be at a brake line, fitting, hose, or caliper/wheel cylinder. If leakage is severe, fluid will be evident at or around the leaking component.

Internal leakage (seal by-pass) in the master cylinder caused by worn or damaged piston cups, may also be the problem cause.

An internal leak in the Antilock Brake System (ABS) may also be the problem with no physical evidence or visual fluid leak.
