BRAKES FELL SPONGY EVEN AFTER REPLACING BRAKE BLEEDING THE MASTER CYLINDER AND BOOSTER. AFTER BLEEDING THE MASTER CYLINDER AND EACH WHEEL STILL THE BRAKES GO TO THE FLOOR AND MUST BE PUMPED TO GET A GOOD BRAKE. THIS PROBLEM DID NOT START UNTIL THE LEFT FRONT CALIPER WAS REPLACED IS THERE AN IN LINE FUSE THAT NEEDS TO BE TAKE OUT WHILE BLEEDING THE BRAKES OR NOT. THANK YOU.
No. There is no fuse that needs to be taken out when bleeding the brakes. Sometimes it just takes a good while to bleed a system.
Brake pedal feels spongy or has excessive travel
- Check the brake fluid level and condition. If the fluid is contaminated or has not been flushed every two years, clean the master cylinder reservoir, and bleed and flush the brakes using fresh brake fluid that meets the manufacturer’s recommended standards.
- Check for a weak or damaged flexible brake hydraulic hose. Replace the hose and flush the brake system.
- If the brake system uses drum brakes front or rear, check the brake adjustment. Inspect for seized adjusters and clean or replace, then properly adjust.
The master cylinder should be bled before connecting it to the system. Usually referred to as bench bleeding. Once that is done hook it up and start at the wheel furthest from the master cylinder. Usually the rear passenger side. Bleed until there is no air. Then move to the drivers rear. Then the passenger front and lastly the drivers front. If the pedal still has to be pumped up to get any kind of pedal, Then you didn’t do it right or there is a leak in the system.
