I can’t fix my spongy brakes. I have replaced all brake pads, master cylinder, a rear caliper and have bled it several times to no success. Someone tells me to change the brake booster but that doesn’t seem correct. How do I fix this?
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.
I had this problem with spongy brake changed the master cylinder. Booster pump. Abs pump. Nohting worked. Then I read on line it could be the rear caliper because the rear caliper has the emergency brake built into the calipers this type of screw piston could give a problem. Sure enough when I changed the right side caliper. The brakes became hard again. Thanks for the advice. Hope’s the helps. Also u can teĺl by pressing on the emergency brake paddle it should be hard, no slack. Before I fixed it there was some slack . After there was no slack.
