Well, I had a busy day on the Jamis yesterday! Got the required tools back at lunchtime so removed the chainset from the Saracen.
It too was absolutely filthy so stripped it right down and gave everything a good clean!
With the chainset off I could look properly at the rear U-brake. One arm was stuck on the frame but I managed to free it up with some WD40 and some brute strength!
The problem was that the brass bush was stuck to the mount and stayed there when the brake body came away.
Got everything off in the end but it means some extra work on the brake before its ready to be re-fitted.
All cables are in place now and hoping to get the brake functioning today.
Got the front one on and working though, so heres a few pics of how she's looking....
I'm going to keep my eyes out for another XT U-brake thats in better condition than the current rear as its got loads of damage from chain suck
