My rear passenger brake is locking on. This happens mostly as I start off. If I back up it usually unlocks. I have also noticed that it is starting to grab when Im driving. I have recently replaced both rear drums and shoes along with kits. While this truck has 246000 kilometers it has been well maintained. My local jobber say it could be the emergency brake cables or the clutches(?) Not sure what he meant by the clutches. He pulled the cables and stretched them about. It worked fine for an hour however it is now as bad as ever and has now started to grab when im driving. I noticed it grabbing at around 80 kilometers(50 miles) an hour.

GRABBY BRAKES Oil, grease or brake fluid on the linings will cause them to grab. The cure is to identify and eliminate the source of contamination, then replace the linings. Badly scored drums or rotors can also grab. Resurfacing may be needed.

DRAGGING BRAKES May create a steering pull and/or increased fuel consumption. Caused by weak or broken retracting springs on drum brakes, a jammed or corroded caliper piston, a floating caliper with badly corroded mounting pins or bushings (uneven pad wear between the inner and outer pads is a clue here), overextended drum brake self-adjusters or a sticky or frozen emergency brake cable
