My brakes failed so we took it to a Monro muffler and brakes. There we found out someone had put ATF in the master brake cylinder.

We only had our oil changed in March 06 then we had an accident in August 06. When we got the car back a month later from the dealer, the anti-lock brakes started going off. We had no problems after the oil change…only after the dealership fixed it.

The master brake cylinder was ruined and the dealership is claming it was the oil change place.

How long would it take ATF to go through the brake lines and do this damage? Was it the oil change or was it the dealership?

the car had front end damage and also the speed sensor was replaced. I have paperwork for all repairs for work done. It was only taken to those 2 places, I am thinking it was the dealership that did the front end work.

The seals in the braking system were designed for brake fluid, not ATF. It is going to be hard for you to prove the oil change place put it in. You must replace any component that came in contact with the ATF and flush out the rest of the system. It looks like you are stuck with the cost. In the future, don't have anybody touch the master cylinder, only have them report on the level.

ATF will start causing damage almost immediately. The rubber components internal to the brake system will be attacked almost immediately.

It may be hard to find out who did it, and even harder to PROVE who messed up. Check the paperwork from the oil change place to see if they checked and serviced the brake fluid; it should be listed on the work order. And check the repair order from the dealer and see if they worked on the brake system.

Given that AFT will damage the system very quicky, I'd be looking at the last place that worked on it.

ATF can destroy the complete brake system. Master cylinder, anti-lock pump and control system, brake calipers, etc. The entire system needs to be inspected by an expert and probably replaced.

Quite honestly, unless you have a record of the oil change shop toping off your brake fluid or changing it, you're out of luck with both the dealer and the quick change shop.

I would look into the company that fixed your car after the accident. They were the only ones who had anything to gain by using trans fluid instead of brake fluid. Check the paperwork they gave you on the car. If they had any reason to service the brakes, they probably used the wrong fluid.

the dealers are pro,and its hard to think the dealer would do that,the oil change place are not pro and i would say the oil change place did it also did the dealer do any work on your brake system form the accident
