Chevy C/K Series Maintenance and Repair
I have had problems for quite sometime with the right rear wheel locking up when applying the brakes. I installed new rear shoes and it really compounded the problem. I then installed a new master cyl. & wheel cylinders and the problem still exists. Sometimes it feels as though the drum is warped as I get a vibration when applying the brakes but not always. I checked the drums and they are within .010 roundness. Is there any way to check the combination valve? This valve is pretty expensive and I hate to replace it and still have the same problem.
