    WARNING:

    Disc brake pads are adhered to the caliper piston using an adhesive patch. The disc brake pads must be separated from the caliper piston. Do NOT insert the pry tool through bridge window to pry against the piston face. Prying at this location may damage the brake caliper piston. Failure to follow this warning may result in brake system failure and/or personal injury.

    Loose the inner brake pad (1) by twisting a screwdriver (4) between inner brake pad (1) and brake caliper (2).

  10. 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.

  11. Rotate the brake caliper (2) upward and support with heavy mechanics wire.
