Honda CBX Z/A Complete Brake Caliper Rebuild Kit. This kit uses OE or OE quality pistons and quality seal kits that we use on our rebuilds and restorations.
Kit consists of ;
2 x Front caliper seals
1 x Rear caliper seal
2 x Front caliper pistons
1x Rear caliper piston
3 x Bleed nipples
We have found cheap after-market stainless pistons at a similar price to be undersized and therefore they leak break fluid.
The Honda OE part 45107-415-006 - Front Piston
The Honda OE part 45107-410-006 - Rear Piston
A caliper seal rebuild kit can be found here if pistons are not required.
