Re: Fiddling with rear calipers
In my experience, the sliding pins get a bit rusty and sticky. You can take them out and lightly emery them so they slide more smoothly but in the end I never quite got them sorted to my satisfaction and had to bite the bullet and buy the pukka caliper repair kit.
This was quite dear at £14 (in the 155 kit you get 4 new sliding pins, 4 rubber boots and a tube of grease) but I have to say the new pins made a huge difference, even though my cleaned up old ones seemed to be not much less sticky.
Another thing to try is to take the pads out and check how tight they are in the caliper. The '55 has then slide into slots in the calipers and if the pads are old (as they never wear out) the backing plate rusts on the edges, expands and then jams in the caliper, so it doesn't move very much.
Take the pads out and file the ends of the backing plate so that it is a loose fit in the caliper slots. All that sorted my calipers out a treat, so hopefully yours will be sorted too.
No bullets for Chaingun..
