Has anyone changed their brake proportional valve? If so, with what, a OEM or aftermarket? Is there anyway to tell if mine is bad? I want to do something to fix my weak rear disc brakes. I would hope this has been done before quite often since many people have this problem.

Thanks

 

The most common reason for weak rear brakes is a failed master cylinder. That is what I found on my car.

So while I was at it I replaced the master cylinder and brake booster. What a big difference it made. After all, the newest 3rdgen car is 10 years old. That's a lot of brake applications on an old master cylinder and brake booster. So I figured it's cheap insurance.

Have you tried looking at something from Bear?
They might have something.

 

I looked on the Baer website , and it appears that they only sell kits of brakes calipers and rotors.

Anyone else have any advise?
