It should no longer be possible to remove the protective cap from the brake caliper housing by hand.

CAUTION:

Risk of damaging the protective cap and gasket.

Do not tilt the brake caliper piston.

-- Press the brake caliper piston lightly on the protective cap.

-- Blow out the protective cap with the nozzle of the compressed air gun (maximum 3 bar (43.51 psi)).

The brake caliper piston thereby jumps on the brake caliper piston.

-- Press the brake caliper pistons into the caliper using :T10145 .

Inner sealing lip of protective cap will then engage in the brake caliper piston groove.
