Apply a light coat of lithium soap base glycol grease to the entire circumference of a new rear disc brake bush dust boot where it contacts the rear disc brake cylinder mounting, and the entire inner circumference of its both ends.

NOTICE:

Apply a sufficient amount of lithium soap base glycol grease to the entire circumference of the rear disc brake bush dust boot and rear disc brake cylinder mounting contact surfaces.

HINT:

Apply at least 0.3 g (0.01 oz.) of lithium soap base glycol grease to the rear disc brake bush dust boot.

Install the 2 boots to the mounting.

Apply a light coat of lithium soap base glycol grease to the rear disc brake cylinder slide pin where it contacts rear disc brake cylinder slide bush.
