I tried to rebuild my caliper with the Centric 14362022 kit. The seals fit but ripped when I pushed the pistons it. It seemed tight with the SS sleeves.
I bought a remanufactured caliper from car parts.com for $196. That fit perfect and I got to keep my original caliper. It was Cardone A1184455. Just had to get different bolts and brake line adapter.
I just ordered a set of new 4 piston calipers from Firebird Central, new castings with stainless steel cylinders, comes with the short hard line to brake hose. I'll let you know how they look once they get here.
