Hi, wonder if anyone out there could she some light on a problem I am having with my rear brake caliper.
Went to change the rear brake pads, boy did I have a problem getting the caliper off the bike, I thought at first the pistons had seized up as I could not get them to retract, anyway got as far as getting the caliper off the bike, changed the pads but for the life of me I can't get it back on with the new pads in place.
I cleaned up the pistons, now if I use a g clamp on one piston it goes in no problem, the other one comes forward, swapping over the clamp I can do the same with the other one now coming forward, if I get both pitons just about the same level and use the g'clamp to push them both back at the same time I get absoloutly nothing, rock solid, I could slacken the bleed nipple I suppose and push them both back but don't now if I would end up with the same problem only this time with the caliper back on the bike.
I marked both piston with a marker pen as a level guide, both can be pushed back to the same positon, both marks level with each other and no further, at least not far enough to let me get the caliper on with the new pads in place, is there something I am missing.
A further question what is the allen key at the side of the caliper for?
Any assistance would be greatly appreciated.
