nathant Posted May 13, 2010 Share Posted May 13, 2010 hi im sure that r6 calipers are the same,but il tell you a trick how i free up seized caliper pistons.half fill a bucket with hot water frm the kettle.hang the caliper over the bucket still attached to the brake line but not in the water.leave it there for 20mins the steam rising will loosen all the crap trapped round and behind the piston.you shld then be able to pump the piston out and clean the seals and the rest of the caliper and put back together.hope this helps Link to comment Share on other sites More sharing options...
Moderator mervin Posted May 13, 2010 Moderator Share Posted May 13, 2010 Where are you friedegg if you are in the uk contact Nick Chambers RDbitz he will sort it out for you, very likely rebuild it using stainless pistons, it will be better than new and cheaper than a replacement, you could get a secondhand one from ebay but there is no gurantee it will be any better than yours Merv Link to comment Share on other sites More sharing options...
Speedshop Posted May 13, 2010 Share Posted May 13, 2010 Pistons can appear to be really in there tight, but there are ways to get them out. unless the caliper has been badly butchered I wouldn't change them for unknown used items. My trick involves a big propane tourch and a 100psi air line. I've not been beat by a seized piston yet! Link to comment Share on other sites More sharing options...

Beware red hot cannon ball in the shape of a caliper piston, make sure the piston cannot fly out and hit anything if you try this method, most of all keep your fingers out of the way, a grease gun can be used to hydraulic em out as well Merv Link to comment Share on other sites More sharing options...
2 Wheels Posted May 13, 2010 Share Posted May 13, 2010 Soak a small towl in boiling water from the kettle, spray wd40 on the piston, wram the caliper in the towl and leave for a while till towl starts to get cold, the hot towl will expand the caliper the wd40 will make its way into and arround the piston, then pump out the piston with the brake leaver, Dont burn your hands.
