Rear passanger brake running hot

Hi,

I recently did a brake job on my 2000 Cirrus (replaced wheel cylinder, pads, hardware kit, and drums turned), and sometimes the rear passanger brake is running hot (very inconsistently - it will do it one day and not the next). I opened it up twice and inspected - everything has been assembled correctly and the adjusters are greased and move nicely. It worked very well for a while, and then I smelled it and noticed it was running hot. The feel of the brakes is very good: pedal is right up and there is no significant braking bias (in either the fronts or the rears) when you hit the brakes hard. Any idea's?

Some interesting things that I did notice:
- when I did the brake job, the rear pass wheel cylinder had been leaking, so it was really gummy inside. This is one reason I had the drums turned. I measured the drums and they are in spec.
- it was significantly harder to bleed the rear pass then any of the other wheels, including the rear driver side.

Help me out if you can. Thanks.
