Many thanks in advance Lee Leave the caliper conected to the brake line but take the caliper off the bike. Boil the kettle Get a towl and put it in the sink pour the water from the kettle into sink soaking the towl Get gloves and bring the roasting towl out and wrap it arround the caliper leave it wrapper on there and boil the kettle again before the towl starts to cool down pour the hot water from kettle on it again anytime now you can start to pump the brake leaver hard and this should eventualy push out the piston What you are trying to do is heat up the calliper quickely without heating he piston, This should give you enough room to free the piston Good luck. There are other methods also but if ya dont have any tools then this is your best bet. Link to comment Share on other sites More sharing options...

Paulwhite Posted June 20, 2010 Share Posted June 20, 2010 i've used a variable grip and turned the piston around whilst pulling, evetually it come out yeah that works for me! take caliper off, get someone to push the brake lever in while you get some grips on it , twist and pull.
