Rebuilding Callipers

[slip]

Is there anything special I need to know/do when rebuilding R32 GTST alloy opposed 4 piston callipers? Im getting them from japan and im thinking I might as well rebuild them before I put them on the 31, do it as well as i can first off.

any tips/trick/things to watch out for/special tools needed?

no special tools req
Its a simple piston out, seal in ,piston in job
sometimes you get lucky and the boots stay on sometimes they don't

How do you get the piston out? I'm thinking of rebuilding my Corona callipers at the moment, according to the Gregory's book I need an air compressor to blow air into the thing to get the piston out...

[dattoman1000]

compressed air is the easiest way

watch your fingers if using compressed air, its easy to loose them, the pistons come out in a hell of a hurry if you arent careful, but unfortunatly its only usefull to get one piston out (or on opposed designs, one per side) the other you will have to play around with and try and get it out.

If there connected on the car you just take them off (leave brake line on) and pump pedal a few times...just be ready for brake fluid to go everywere.

Thats how i do mine.

If you have a single-piston caliper, put a piece of wood on the other inner side of the caliper to catch the piston when using compressed air, instead of it bashing itself or your fingers....
