Repair. Bendix and Teves calipers

Clean the calipers from dust and dirt. Remove the piston from the caliper, which can be done using low pressure air supplied to the brake cylinder through the hole for connecting the brake hose. Remove the dust cover from the groove in the piston and the O-ring from the groove in the caliper bore.

Wash all parts in methanol or clean brake fluid and wipe dry.



When assembling the caliper, use a new piston o-ring and dust cover. Lubricate the piston bore in the caliper and the o-ring with clean brake fluid. Install the o-ring into the caliper bore. Install the dust cover on the piston so that the inner diameter of the cover fits into the piston groove. Insert the piston into the caliper and at the same time push the outer edge of the dust cover into the caliper until it locks into place (see fig. 9.17).
