Brake service disaster
Start to drive home. We made it one exit and the brakes were dragging. I drove the car immediatly to a local Chevy dealer and dropped the car off. They could not find anything wrong. I picked up the car, drove it around and right back to the dealer. The dealer was focused on an ABS or traction control problem but couldn't find anything wrong. They suggested I just drive home with the TC off and get the car serviced when I got home.
So we drive home. Had 5-6 instances where the brakes would come on and stay on for several minutes during the trip. Something not right here.
This morning, I take the car into the Chevy dealer where I bought it and they take it for a test drive and agree there is a problem. Upon inspection, there is power steering fluid in the brake fluid resevoir
The dealer says it will be $4600 to fix the brake system and that does not include new rotors/pads which are worn, but not worn out. Power steering fluid ruins all the rubber seals and lines so everything must be replaced.
I have talked to my insurance company and will hopefully get everything covered by the shop who did the work, but this totally sucks.
Both hydraulic fluids
I would never substitute one for the other,however i find it hard to believe that power steering fluid would ruin rubber components......
aren't power steering lines rubber???

Power steering fluid is a petroleum hydraulic oil, which is like or the same as automatic transmission fluid.
The materials that are compatible with glycols are usually not compatible with petroleum fluids and vice versa.
Some one really screwed this up.
On a few vehicles, like my rainy day Astro van, the brake booster runs off of the power steering pump instead of the vacuum system. But the brake fluid is definitely DOT-3 type.

That sucks!
I have an aquaintance that had a doddge truck - he for some reason decided to top up the master cylinder (a no-no anyway....) and he used power steering fluid.
Oooops.
he called me talling me his brakes were acting funny, and when I started looking the rubber gasket on the reservior was swelled up......Hmmmmm....
I asked him if he had been messing with the brake fluid and he gets this blank "oh sheeeezot" look on his face.....
That is an expensive problem to fix.
I hope you get some help from the shop that did this -
best regards -
