A brake fluid leak in the system would do that. Check the brake fluid reservoir. If it is empty you are in need of brake work asap!


What happens when you run out of brake fluid?

The brake pedal will go to the floor but will have absolutely no effect on stopping the vehicle. When you push on the brake pedal it moves the fluid through metal tubes (called brake lines) to force the brake pads against the rotor which slows and stops the car. No fluid means nothing is in there to make the brake pads engage the rotors.

Brake fluid is running down the clutch pedal and when you mash the pedal the pedal remains on the floor?

Actually if the fluid is coming down the clutch pedal it is probably your clutch master cylinder going bad or the seal around it. No worries it is a cheap fix. If it is coming down the clutch pedal it has nothing to do with your brakes. Some people well most use brake fluid for the clutch.
