Brakes problem V8 Four Wheel Drive Automatic 310000 miles

i have had my right rear brake lock up twice on me once while pulling out of a parking spot and once while driving down the street. i pulled the rear drums thinking the shoes were prob worn to rivets but that was not the case. drums came right off with little effort and brake shoes were fine. my mechanic wants to change the left front hub assembly because the ABS sensor is not working. i told him to change the right rear wheel cylinder as well because that is all i can think of that could stick causing the brake to lock up tight. the brake will release but only after pulling up an back causing it to break loose. while up on jacks spindles turned freely an no noise coming from diffrential. any ideas? thanks

The right brake is locking up because the brake shoe has lost its strength and is sprung and catching (wedge) on the drum instead of sliding. Replace the rear shoes with good AC Delco units and you should be fine.

Here is a video that will show you what you are in for when doing the job.
