When I managed bike-shop during university, we had lots of bikes come in with stuck seatposts. They'd be mangled and scared-up from endless twisting trying to free them up. We would just spray PB-blaster on them and let sit overnight. By next morning, 1/2 of them would have seats completely lowered by themselves after the PB-Blaster dissolved corrosion from seatpost.
Me and my buddy are rebuilding the caliper this weekend. But I guess since I have some PB blaster sitting around Ill give this option a go and see what happen. Thanks for the tip! Ill let you know how it goes
