Q: Brake pedal going to floor

asked by on

The brakes are out, and the brake pedal is going to the floor.

The complete brake system will need to be inspected to see if a major brake fluid leak from a component or metal lines is leaking. If there are no leaks and the fluid is full in the master cylinder, then the most likely cause is a master cylinder internal failure, which may require replacement. I recommend having a mechanic, such as one from YourMechanic, do a complete brake inspection.
