1. Brake Caliper Bolts
   NOTE:

   It is not necessary to loosen these bolts to remove the brake caliper.

   Only the bolts -10- are loosened and removed.

2. Brake Pad Retaining Spring

   Make sure it is installed in the correct position

3. Guide Pin

   Push from the outside toward the inside through the brake caliper and the brake pads.

   NOTE:

   Make sure it fits correctly inside the brake caliper. The groove on the guide pin must fit inside the groove inside the brake caliper.

4. Brake Caliper
   • When doing work, do not allow to hang from brake hose, rather suspend it from the body using bundling wire
   • Except for "Brake Pads, Removing and Installing " and "Front Brake Caliper, Servicing", no further repairs should made to the brake caliper.
   • Install hose so it is not twisted
   • Refer to BRAKE CALIPER, REMOVING AND INSTALLING, CERAMIC BRAKES 1LW 
   • Refer to BRAKE CALIPER, REPLACING, CERAMIC BRAKES 1LW 
5. Brake Pads
   NOTE:

   The inner pad is equipped with a cable for the wear indicator.

   • The brake pads may have a protective film on the back of the pad. Peel off the protective film before installing.
   • Before installing the brake pads, clean the pad guide surface and coat it with a film of Polycarbamide grease.
   • Always replace on both axles.
   • Refer to OVERVIEW - FRONT BRAKES, CERAMIC BRAKES 1LW 
   • Check the brake pad thickness.
