Any time a part of your braking system begins to fail is a major safety concern. Some symptoms of a bad master cylinder are: soft or spongy brake pedal, brake pedal won't hold pressure at a stop, and slowly goes to the floor, creaking and jerky movement of the brake pedal when stopping.

This brake master cylinder is a great replacement and offers good cost savings over a dealer unit.
