Removal Procedure

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove the brake caliper from the brake caliper mounting bracket and support the brake caliper with heavy mechanic's wire or equivalent. Do NOT disconnect the hydraulic brake flexible hose from the caliper. Refer to Front Brake Caliper Replacement .
    WARNING: Refer to Brake Dust Warning .
    CAUTION: Support the brake caliper with heavy mechanic wire or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.
  2. Remove the brake pads (1) from the brake caliper bracket.
