2006 Chevy Malibu Brake Issues
Ok, so we've been having an ongoing issue with my mom's brakes and I figured I would post on here to see if any of you car gurus have had any similar issues or ideas for us. Here's whats been going on:
The car was bought in 2006 and had no real problems until this past fall. The brakes would basically lock up and the car couldn't be driven anywhere. We took it in to the dealership to see if anything was still under warranty. The ABS unit was so they replaced that this past fall along with the rear brake pads. They mentioned that they had trouble closing the calipers but it was stopping fine so we thought it was fixed. Then towards the end of April the brakes started locking up again. My mom said it felt like the emergency brake was on but it wasn't. She would let the car cool off for 20-30 mins and then it would be fine for a little while (meaning hours, days or even a couple weeks). It happened a few more times and she finally took it in. They said checked it out and couldn't see any visible problems but that it could be either the master cylinder or the brake boosters. They decided to change the brake boosters. We got the car back and it was running fine. We even drove it down to Lexington and back this weekend with no issues at all, until last night when it happened again.
Now, I'm starting to get skeptical about this dealership but they have seemed to be pretty straight forward with us and gave my mom a rental car to use at no cost to her this past fall. We've even called around to other mechanics and checked with our normal mechanic and he's as stumped as the dealership.
So, has anyone dealt with this kind of problem before? Any solutions or ideas?
