Dismantling-reassembly

Dismantling-reassembly

Place the caliper in a vice, fitting the protections, then proceed as described below:

1. direct a jet of compressed air into the brake fluid inlet hold in order to dismantle the piston from the caliper case;
2. undo the air bleed screw and remove it;
3. remove the seal;
4. check the components; the piston and caliper case must not show signs of friction or seizure; if they do, the caliper complete with piston should be replaced. It is nevertheless always necessary to replace the dust excluder (1) and seal (2), and to check that the bleed screw (3) is not blocked.

Use a solution of FIAT LDC detergent in hot water to wash the metal parts.

NOTE To refit the brake caliper, reverse the procedure for removal.

Lubricate the parts concerned with brake fluid before final assembly.

Before fitting the piston in the caliper case, fit the dust excluder on the rear end of the piston. Insert the piston gradually, taking care not to damage the dust excluder.
