T4 Post Icon Rear nearside brake sticking on

So, I had a problem with the rear caliper seizing on and the wheel getting exceptionally hot/squealing. I cleaned the caliper up, made sure the pads could move freely etc, re-assembled. Same problem, actually a bit worse. Suspected the caliper - looked like it had had a seal kit by previous owner. Fitted a new caliper today and still have the problem. It's not so bad now - the wheel just gets warm - but still warmer than all the other wheels. I have checked the handbrake cable and it's slack enough so that it wouldn't be leaving the brake on. I'm just totally stumped now. It's only this wheel that's a problem - all others fine. What have I missed?

Did you take apart the slider pins?

If not polish these with a good chrome /metal polish and remove all traces of polish.

Apply copper slip grease.

Reassemble.

Thanks. i did take the sliders out and re-grease them - they weren't in great condition though. I'll revisit them.

I use a whit ceramic grease for the slider pins. Copper grease tends to dry out and the pins get stuck again after a few months.

Well, I cleaned the sliders up, re-greased, re-assembled, half hour test run and it's still hot. Took it all apart again and have noticed that the pads have uneven wear. They are worn at a slant. I think this could be the issue. The wheel bearing is fine and disc seems fine too, although a bit grooved. I suspect that the old caliper was seized at a slight angle and previous owner free'd the caliper, used a seal kit, but then re-used the same pads... so now they're trying to run flat above the surface, when actually they're not flat and so causing friction. I'll pay a visit to Halfords tomorrow and hope that they have some pads in stock. Need to get some quick as we're going to Wales on monday.

Sometimes the rubber brake hoses can collapse internally and cause a flap which wont allow the brake fluid to flow back and so the calliper wont release all the way.

not to pop your bubble but pads that don't make good contact should still not drag unless something else is amiss. the auto adjust can be fussy on the rears. did you back in the calips properly (turning and pushing not just turning)?. Also in another recent thread it was discovered that the auto adjust in the rears was contaminated and causing the pads to drag.
