 spongy brakes
My 98 Windstar started having spongy brakes when we drove with the emergency break on and heated them up so much that the pedal went straight to the floor. After we realized what was going on and took the emerg brake off the brakes came back but every once in a while right at the end of the braking action they go spongy and chatter but never straight to the floor. THe mechanic has bled them manually and with a bulb 5 times each no air. We disconnected the abs by removing the fuses and it still does it. Recently we replaced the computer... still does it. I was thinking from what I've read here and on other sites that replacing the master cylinder isn't going to help either. What about a rear brake adjustment? |
