Overview

A GiroDisc front caliper dust boot kit for the 2014-2025 Porsche 911, 718 Boxster Spyder, Cayman GT4, Cayman GT4. Track heat hardens and cracks the rubber dust boots around the caliper pistons, which lets grit reach the piston bores. Fresh boots keep the pistons clean and protected, and they make a worn caliper look like new again.

Why replace the boots

Dust boots seal the gap between each piston and its bore. After a few too many hot track days, the rubber hardens, shrinks and splits. Grit and moisture then reach the piston surface, which can score the piston and wear the seal behind it. Replacing the boots before that happens protects the caliper and keeps it looking fresh.

Made to GiroDisc's specification

These boots are made to GiroDisc's specifications for this caliper. Clean each piston and boot groove before fitting the new boots, and check the piston seals while the caliper is open. If the seals are tired too, GiroDisc's caliper rebuild kits include seals and boots together.

Protect the caliper

GiroDisc recommends pairing fresh dust boots with its titanium pad shields, which cut the heat that reaches the boots and pistons and lengthen service intervals.

What's Included

Enough dust boots to rebuild one caliper. Order one kit per caliper, so a full front axle takes two kits.
