Left rear brake Sticking

Question: I have a 1988 Ford Mustang w/ rear discs and no apparent ABS. Replaced calipers and pads. Left rear brake fails to release after using E-brake. Replaced caliper again. Same deal. Answer: Sounds like the problem is in your Park brake cable. Disconnect them. pull the lever and measure. Release the lever and measure to make sure they are releasing. If not, replace the cables and make sure they are routed correctly. If it fails to release without using the park brake, then you need to replace the caliper hose.(most common)
