It could be an internal or external leak. Check your fluid level and if it is low or empty, top it off and look for a leak under the car while someone pumps the brake pedal. If the brake fluid level is full, most likely the master cylinder is leaking internally. Brake Problem Troubleshooting Comments are closed.
