Brakes

[ViperRon]

Compressed air dangerous, Grease gun works great but if it is still stubborn there is another way. Plug the brake hose fitting with a properly fitted bolt put it in a pan of water and heat it. Treat this as dangerous also as the piston may pop out quick so a covered pot is best and not in your kitchen!. The heated water will soften the old seal and the heat will force the piston out. Grease supplies great pressure but hot water will soften the rubber ring also and can work when nothing else will without blowing your head off.
