need help on brake rebuild. piston issues???
I'm rebuilding the brakes on a 1988 CBR600.
The front pistons are covered with a cap
one of the caps on one of the front pistons came off when I took it off the bike.
It appears to have had some sort of white adhesive holding it on.
Anyone have any ideas on what type of adhesive could've been used and even if it is someting that can/should be done, or if I should replace the whole piston?
I put 2 pics up to show the cap off the piston and one of the other pistons with the cap on it.
any help would be greatly appreciated
