Sticky rear brake.

[darrsi]

Best stuff to use is brake cleaner and red rubber grease to achieve the same - there is a risk wd40 and similar can damage the rubber seals although admittedly I've used that and gt85 in the past with no ill effects. See the link for a good guide.

Once a piston is cleaned, I smear it lightly with red rubber grease before pushing the piston back into the caliper, and wipe off excess which will attract dirt or run off onto the braking surfaces. As the pistons might need more persuading to move this time, you could try wd40 or similar to free them up but would not use too much too regularly - my 2 pence worth. Rest is covered in the guide I think. Back of the pads and brake pins, use a little copper grease not the red stuff.

I'm only on about the lever pivot with the WD40, i wouldn't go near the calipers with it.


Calipers are strictly brake cleaner only, as it leaves no residue at all. I've used a normal degreaser spray before and the residue left behind caused the pistons to misbehave, even though i used plenty of red rubber grease.
