Brake rebuild on my fc..... brake piston help.
Probably for the first time since it rolled off the assembly line, my brakes are getting tlc.
So i blew the pistons out of their bores with compressed air and only had to unstick one piston very carefully with a set of channel locks
I have a good bit of surface rust on several of the front pistons that will require some attention with a wire wheel. It's far enough away from the inner bore seal that it shouldn't be a big deal especially if i polish it down but i'm curious of what others did.
Did you clean up your "bad" pistons and reuse them without a problem or did you buy new ones, if so, why?
I'm concerned about proper sealing. I dont want to have to do this job twice.

Mine were rusted, so I used a wire wheel, and some sandpaper. Got the pistons real smooth, than polished them, lubed them, put the gaskets on them, and slid those things back into the hole. Oh, I hope you didn't already, but DON'T SPLIT THE CALIPER IN HALF! Oh yeah, I didn't notice any difference in stopping power, or performance. The one thing that held me up was that my brake master cylinder said its farewell at the time, so I got a new one.

Thanks! I'd give you a firm handshake if i could.
My BMC is for sure dead. Something in side it is either stuck, clogged or just generally not working. I trouble-shot all the lines checking for kinks/bends.... The caliper pistons weren't terribly screwed but even with the brakes OFF the car, the brake pedal still had a shitload of pressure behind it.
Again, THANK YOU SO FREAKIN MUCH. I was close to doing what the fsm said and replacing the pistons..... $25-50 per piston isn't cheap.
