Every time I clean up my eight pistons, the difference in feel is remarkable. I do it every front tire change now and it always makes me happy!
Docc,how far do you break them down? Take off the hoses,pull pistons,re-bleed.Or keep intact,just spray with brake cleaner,scrub and blow out.What do you lube the pistons with?
Sorry for the slow response while I was away at the South'n Spine Raid . . . Thanks coreytrevor and gstallons for the excellent replies!
I don't remove the pistons, but spray them off with CRC Brákleen before retracting the pistons (remove the old fluid from the reservoir first), chock the pistons and move one-at-a-time in and out out spraying cleaner on the circumference. I am relying on the fresh brake fluid (simply "DOT 4") for the lubrication. I keep moving from piston to piston until they all move out uniformly. Clean and polish the pad pins, a light smear of silicone grease on the pins.
I never thought to rotate the pistons, use a brush, or assembly lube. What a great forum. Always learning!
