I recently blew out a rear wheel cylinder on my Z and the brake light has turned on I found out that it is a combination valve or better know as a propotioning valve but I cant get one anywhere even the manufacturer has discontinued the part does anyone have any advice on what I can do so I can drive my car again?

 

The only other thing I can think of is an aftermarket adjustable proportioning valve. You can get inline ones with or without a gauge. Summit even has a slick one that is a combo adjustable proportioning valve/distribution block, and it also has a built in brake light switch.

 

Ok Thanks man I will try that I was told that no one builds combination valves and they are factory only Guess I should have done some more research instead of trying to go stock

 

I have one off my 91 I replaced for one that works with rear disc. Did you not read the other thread you posted in. The line configuration is two straight up and two straight down and one at the top at an angle.There are different line configurations to look for. I got mine new. Its an AC Delco part. I am special, I have connection. I got it from the wholesaler that supplies the dealers with parts. They are expensive though. But usualy do not go out that is most likely why parts stores dont stock any.
Your wheel cylinder may have just been ready to go and now that it leaks pressure it will make the light come on due to an imbalance of fluid pressure. Make sure your brakes are all bleed properlym when its fixed

 

Yeah I know that my wheel cylinder was probly about to go out and that there was a imbalance with the hydrolics. The switch went bad and it has locked out the rear brakes. I am about to convert to disc brakes soon just need to be able to drive to Alabama to do it
