Q: Rear brakes locking up.

asked by on January 12, 2017

For about 2 years now the ABS light and brake light have been on. One month ago my rear brakes locked up. I cracked open the bleeder valves on the wheel cylinders and very little fluid came out, but enough to free up the brakes to get home. Since I replaced the rear brake hose and metal lines with new ones all the way up to the porportioning valve. Got that done today. Took for a test drive and ABS light and brake light are back on. I feel it is a matter of time before brakes lock again. What do I check or replace next? The porportioning valve?

My car has a manual transmission.
