I got power steering fluid into my master cylinder by mistake. I broke down on the road by having the brakes cease up on me. I had it towed to big o tires and was told that the system has been contaminted with an oil product (power steering fluid I think). I need to fix this and think I can replace the components myself. but don‘t know what to do about the aBs module replacedment and scan tool part?
How much power steering fluid did you get in there? it can't be much. the only way to do it right is to flush out the brake fluid. start by using a turkey baster or a syphon to remove all of the fluid from the master cylidner. then start the flush; you can do that by opening the bleeder valve on the far right wheel then put a hose over the bleeder and pump the brake pedal to get all of the fluid out of that line. then go to the left rear and do the same thing. then the right front and then the left front. keep adding new brake fluid to the master cylinder to replace the fluid that comes out. do that about 3 times and you should get all of the contaminated fluid out of the system, i can't quite understand how the contaminated fluid would cause the brakes to lock. I could see it causing the pedal to fade or drop when hot but power steering fluid is a hydraulic fluid and even though its a different base (petroleum v. mineral oil) I don't see how it would cause the system to lock. I don't think the ABS is a separate issue. I imagine you could open a line on the ABS and pump the brake pedal to try to get the fluid out of there as well. as for the seizing, find out what seized and go from there. the front brakes have calipers that can be rebuilt; rear brakes are usually disc as well.
I suspect any general repair or muffler shop will install this for you.
