- Use compress air to press pistons out of brake caliper housing individually.

Note: Only one piston can be pressed out at a time. Hold the opposite piston in position in the brake caliper housing using a piston resetting tool -a-.

Block the other pistons, e.g. using wooden blocks -b-. Place a wooden board -c- in front of the piston resetting tool to prevent the piston from being damaged when being pressed out.





- Remove sealing ring using assembly wedge 3409.

Note: Make sure the surface of the cylinder is not damaged during removal.

- Thinly coat piston and sealing ring with assembly paste G 052 150 A2 before inserting.





- Insert sealing ring into brake caliper housing.





- Install dust seal on piston.





- Push piston into brake caliper housing, applying even pressure.

Note: The dust seal must be firmly seated in piston groove, press home using a piston resetting tool if necessary.
