Can rear callipers become jammed or “sticky”?
I have a wobbly brake disc problem new bells& discs but still getting brake binding at one spot on the disc.
can the callipers become siezed? the callipers are free on the mounting bolts and move in and out as expected.
Anybody used Brake Calliper Specialists for a rebuild??
Puzzled…from Suuuuuufulk
Have you checked for residue of gravy?
I had my calipers refreshed by Hofmanns. Thinking about it I may have that set somewhere if you want to try them…
I used SJ sports cars to rebuild my calipers, quick turn around and a good price.
^^^ I traded mine in for new.
BCS quoted £202 for a pair without any special paint. cheaper than new ones but could I attempt the rebuild myself?? 
Loads of gravy in there! 
Are sure the caliper causes the probelm? If your brakes do bind at a single point of the disc your brake disc may not run rectangular with the caliper mounting plane.
I found this picture somewhere on the net showing the problem and how to measure it using a dial:
You may use a more simple setup by just letting something point rectangular to the brake disc and just touch it and then turn the brake disc by hand. If you observe a changing gap the disc, its mounting or the wheel hub imay be the cause for your brake studder.
The symptoms of a sticking caliper are usually overheating brakes or dragging brakes and increased pad wear. If the guides of a sliding caliper are worn out you may have brake studder as well.
Would that be DOT 4 or DOT 5 gravy 
Are the pads wearing evenly across the face? - Had a prob some years ago and the steel upright on one side had somehow had become distorted so the caliper was not operating in the same plane as the upright - causing all sorts of issues
12% proof
12 thou out at the outer edge of the new hub…cant be too good?
If 12 thou means 12/1000 inch (about 0.3mm) than this will be way too much.
My ex-girlfriend bought me a de-cat pipe for Christmas from the same place you got you discs and bells from so I wouldn’t surprise me if there was run out. The flanges were welded on the p**s so it went back and they even moaned that I didn’t want it! What’s equally annoying is I never got a replacement Christmas present.
Problem resolved…company involved replaced faulty part without question .
Thanks all concerned.
