Q: Spongy brake pedal

asked by on

The brake pedal is spongy, and goes almost to the floor before braking begins.

The brake master cylinder is most likely leaking internally; it needs to be tested, replaced then bled out of air. If the system fluid is not low, then this is the most likely cause. I recommend that you have a mechanic, such as one from YourMechanic, diagnose and repair your spongy brake pedal issue.
