Removal Procedure

Caution: Refer to Brake Dust Caution in the Preface section.

  1. Remove the caliper from the mounting bracket and support the caliper with heavy mechanics wire or equivalent. It is not necessary to disconnect the hydraulic brake flexible hose from the caliper. Refer to Front Brake Caliper Replacement .
