    does Insurance cover this issue when Brake Fluid Contamination Causing Problems…can weather cause it??

    Hi, we had an extensive brake job done on our vehicle in October. We got the oil changed in February. The beginning of March our brakes locked up. We took it back to the people who did the brakes and they said, after looking at the oil maintenance sheet in the glove box, that they must have put the wrong fluid in the brake system. On our oil paperwork they only added windshield wiper fluid. It cost $1869.00 to repair.
    Do we have any recourse at all, or should we let it go. Any suggestions would be greatly appreciated.

    We have a 2005 Chevy Uplander. We had an oil change late July. Now we are experiencing the same issues with brakes acting up. Took it to our mechanic he found some bad bearings. We also had rear brakes replaced and still same issues. Our mechanic said it had to do with the ABS and to take it to the dealer where they found the “contamination”. He said we could file a claim with our insurance against the oil change place under “vandalism” on our policy. The dealer wants to charge us $3500 to repair it all. I took the list of parts to our mechanic and he said it’s not necessary to have the BPMV unit (main ABS unit) replaced as there is no rubber in it at all. He’s repaired many vehicles with contaminated brake lines and has never had to replace this unit. Ugh, so frustrated waiting to hear from insurance, which doesn’t look good, our word against the oil change places on how it happened, and we’ll most likely have to pay. So we have the dealer quoting us $3500 and our trusted mechanic telling us no more than $1500. Is this part electro hydraulic or strictly electric? So confused on what to do here.

    I’ve worked on my other bucks in the past. I’m on a 2004 lesabre tracking down abs/bearing problem. Not sure how to get assembly apart on the rear wheel. Looks like em . Brake has to come apart first?
    Thanks Chris.

    Tom: Yes, take off the brakes, the wheel cylinder, then look through the wheel flange and remove the 4 bolts in the 2 oclock, 4, 7 and 11 oclock position. Then pound off the hub bearing.

    The brake fluid light has been on in my car for a while a 2006 chevy cobalt. I added fluid and a day later noticed the light was back on. Its been a few weeks and now it seems like my clutch is going. My dad borrowed my car and noticed the brake fluid light added fluid and said it leaked out.

    • Tech says:

      You must have a leak somewhere. The clutch problem would not be related because it has it’s own master cylinder that is separate from the brake master cylinder. It’s pretty dangerous driving around with a brake fluid leak, so you will want to get that checked out as soon as possible and fixed!!

    So we have a Chevy Uplander that we took into the dealership four months ago to have our brake pads replaced and our fluids changed flushed, and or topped off. Now our brakes have totally failed and we brought it back to the same dealership and they told us that the brake fluid had little bits of rubber in it that got throughout the system. They didn’t even bother telling me the fluid was contaminated! I have not touched the brake fluid at all. They have been the only ones to ever change it. They say it is going to be a 2900.00 bill and my extended warranty will not cover it. Am I missing something? Can your brake fluid just become contaminated and have the rubber swell like that in four months since they just checked out everything?

    • Bob says:

      No, the fluid cannot just become contaminated on it’s own. Someone put the wrong fluid in it. As you say that Dealer is the only one that does ANY work on your Chevy Uplander, then they made the mistake and should repair it at no cost to you.

    So I have a 2006 Pontiac G6. The brakes completely froze up while I was driving the vehicle. I took it to my mechanic he said it had to be the calipers. I replaced all four of those and the brake pads (that were not bad) and couldn’t get two of the four brakes to bleed. I took it back to him they tried to no avail. I took the car to Midas where I was told the brake fluid had been contaminated. Midas is not equipped to work on contaminated cars so they recommended I take it to a dealership. I did that and they said I could possible turn it into my insurance under comp. I did that and they are fighting me all the way. They said they found contamination in the reservoir and the master cylinder and they will pay for that but when they took the ABS module apart they found a mechanical malfunction so they will not pay for that. I was told even with the slightest contamination all the parts need to be replaced. How is it even possible for two parts to be contaminated and not the others? Please help. We have been going back and forth for 3 weeks now.

    • Sammy says:

      Yes, with any contamination, all parts that have any rubber in them need to be replaced. This includes the ABS since there are rubber seals inside. I dont know how they can take the ABS module apart and look at it to decide something is wrong with it. If there is physical damage, then i would guess it is from the contamination.

    How long would the brake fluid have been contaminated before this would happen your car please.The same thing happened my car power steering fluid instead of brake fluid,trying to trace when it happened.
    thank you.

    • Harold says:

      It usually takes a few weeks for the problems to show up. But that depends on much of the wrong fluid was put in the brake system. The more there is, the quicker the problems will show.

    Years ago I had a similar problem. The front brakes started dragging on my Ford truck. Some weeks before the check valve on the booster had fallen apart so thinking it wasn’t very important I just taped it up without the guts. So when the engine was shut down the vacuum in the booster would draw fuel mixture in from the manifold. The first thing to be effected was the rubber disc behind the pushrod for the master cylinder. It expanded and didn’t allow the pistons to retract enough to clear the hole and release the pressure to the brakes. Changing the booster and valve/fitting solved the problem.

      Hi i have a 71 chevelle and my breaks are dragging also, I have been noticing oil leaking out of the valve cover oil filter for the past couple weeks, now the breaks are dragging.. After reading ur comment, I’m thinking It might be a similar problem… Because I haven’t messed with the break fluid and I haven’t taken it to a shop in years, so I don’t think it’s contaminated fluid.. Even though when I opened the reservoir cap the gasket was expanded.. Glad I saw ur comment, letmeknow what u think… Thanks Mang’
