Installation

Installation of a replacement brake caliper piston requires disassembly of the brake caliper, removal of the old piston and seals, cleaning of the caliper bore, and careful installation of the new piston with fresh caliper seals and brake fluid. This procedure is recommended for experienced DIY mechanics or professional technicians. Always replace caliper seals when replacing pistons, and bleed the brake system after reassembly. Consult your Subaru service manual or a qualified technician for proper torque specs and procedures.
