Thanks Brian Crall

Thanks for the info of using zerek fitting and manual grease gun to remove caliper pistons. I had already split my calipers and after much fiddling was able to get 2 pistons out of the front calipers but other 2 no way. Brian posted his grease gun method so I went ant purchased a zerek fitting, $1.15, installed it where brake fluid line enters caliper. Made 2 metal blocking plates with a rubber seal, old tire tube, clamped them on the caliper fluid ports by the caliper body bolts holes connected the grease gun and pumped away. Manual grease gun. Let's just say it worked slicker than.......grease. thanks Brian for the info.
