Evening all.
I am servicing a friend's T100 Bonnie and the rear caliper is in need of a lot of TLC.
So much so, that it was a struggle to even separate the caliper from its carrier. The pins had all manner of nastiness and corrosion (now fixed).
However, I am now at the stage where I need to remove the pistons.
Stupidly... can't believe I did this... I forgot to use the brake pedal to pump them out before disconnecting the brake hose and allowing a load of air into the system.
They're pretty stuck - a gentle attempt with mole grips and inner-tube protection didn't shift them although they have moved maybe 2mm during my recent work.
They are currently swimming in brake cleaner fluid (inside and out) whilst I await a generous soul from this forum to tell me how I can get them out without re-connecting and bleeding the hydraulic system...
My immediate thought was to deploy the trusty heat gun but I don't want to trash the seals.
Any thoughts?
