14 Apply hydraulic oil to the sliding surface around piston
12 and slide it into housing 25.
Note: It is difficult to insert piston 12 into the housing due to
O'-rings 11 and 13. Hold the piston horizontally and push it
into the housing with one movement.
15 Insert the brake unit springs 14 back into brake piston
12.
Note: Insert the springs 14 the same order as they were
found during dismantling.

16 Mount the bushings 20 with Teflon rings 19 and the
plate springs 18 into the bushing holes in cover 17.
Note: Apply a coating of grease to the end faces and
peripheries of the bushings 20 and to the Teflon rings 19
before mounting them, as this helps prevent them from
falling out when the cover is mounted onto the housing.
17 Generously grease the pins 15 and insert into cover 17.
