    So after completing a rear end refurb, first drive I had a few teething problems, managed to sort them all except one; both rear wheels are making an awful squeak/squeal when moving slowly, under 30 mph it's very loud! Gear/braking/engaging handbrake don't make any difference to it.

    Backing plates were initially touching the discs but I bent them back, need to see if I bent them far enough but pretty sure I did.

    Literally everything is brand new except the discs, pads and shoes which in hindsight I should have replaced however they were less than 500 miles on them when the car went off the road.

    Anyone had something similar?

    One of the brake pads or handbrake shoes worn out?

    Noise is both wheels and pads and shoes were very new but possibly either or both are the issue, new shoes and pads coming tomorrow.

    FYI; the issue was the dust guard on the input shaft of the diff was making light contact with the diff body. I had the diff out and replaced the seals and gave it a coat of POR15 so likely pushed the dust cover on too far when reassembling.
