The handbrake drum on my 90 is making a chirping noise if I adjust it enough to hold. It's OK if it is so slack it only just holds. There is also some judder in the drive train - presumably from the handbrake. I can feel it binding at one point in the rotation.
If I jack up one of the back wheels and get the drum rotating, I can see that it is not running perfectly round. It seems to move by up to 5mm.
The drum is fairly new, but apart from it being out of round, is there anything else that could be causing this? Output shaft/bearing/flange maybe?
Trying to exhaust all the cheaper options before I spend out on an x-brake disc conversion!
