Not sure if anyone else has experienced this or not, but any input would be greatly appreciated. Last fall rear brakes would not release. I was able to limp it home with a surprising amount of smoke coming from the brakes and those critters were HOT. I replaced the calipers, rotors and pads hoping this would fix the issue...it didn't. Took it to a local garage who replaced the rear brake hoses and said the proportioning valve was failing. At the time Subaru did not have the valve in stock, apparently there was a shortage last year for this part. I believe Subaru calls it a "PCM or PCV" (pressure control valve or module)...can't remember. Anyways, having the brake hoses replaced did seem to work for a few weeks, but as luck woudl have it the brakes would not release again. So took it to a Subaru dealership and had them look at it. They replaced one of the rear calipers (not sure why), replaced pads and flushed the system. They did not replace the proportioning valve as they could not replicate the problem. So...I am still having the same issue...rear brakes will not fully release. Has anyone else had/have this issue? There are no modifications done to the car. Other than remanufactured calipers, the rotors are OE as are the pads. Absolutely no issues with front brakes. Is it the proportioning valve or is it the master cylinder?
