We got tired of having to cobble together proper rebuild components for STI Brembo calipers, so we came up with our own kit. Each caliper rebuild kit contains a full set of dust boots, piston seals, bleed screws and bleeder caps, and crossover o-rings.
Each kit gives you all the seals and parts you need to refurbish TWO calipers. Get one front and one rear for a whole car's worth of parts. Specify caliper type; note that gold rear Brembos have a smaller piston size than the others, so that gets its own rear kit.

Can't find your piston seals? They are INSIDE the dust boots.
Fits all 2015-2017 Subaru WRX STI, plus 2020-2021 Performance Package WRX.
