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 Anti-Lock Brake System (ABS) may also be the problem with no physical evidence or visual fluid leak.
