Q: Brake pedal going all the way to the floor.

asked by on

My brake pedal goes all the way to the floor. I have no brake pressure.

The pedal going down to the floor usually indicates a loss of hydraulic pressure. Possible causes include a leaking brake hose, a dysfunctional caliper, or a wheel cylinder. Also a master cylinder leaking either externally or internally will cause the same concern. Because brakes are a safety issue, I suggest you have a technician inspect your brake system to determine the cause of your concern.
