Disc brake seals

Stripped the caliper a long time ago so not sure which seals I use, also how do I get the bloody piston back in? Never done this disc brake melarkey before.

use a small blunt terminal screwdriver to get the seals in groove in the caliper - use a small amount of silicon grease to help put piston in - get them started (both in) then I use a small timber wedge to push them home

good luck

Got them sorted, split the caliper and just pushed the pistons in in the vice. Now the problem is that the bleed nipple is 'bleeding even when tightened right down, going to stick a bolt in for a temp solution but is there a seat or something the nipple sits into that may need replaced?
