‘88 Honda CRX, Brake Pedal Goes to Floor
The brake pedal in my ‘88 Honda CRX, slowly goes to the floor after I stop the car. I have to re-pump the brakes again then it would move slowly to the floor shortly after that. This only happens on hot days. Could my master cylinder be bad?
Whether your car is a Honda or a Cadillac, if the brake pedal starts to drop away while holding steady pressure on the brake pedal, you can pretty much bet the master cylinder needs to be replaced.
