| 1. Observing care and security measures, clear a support of brake dust and dirt. |
| 2. Do not unscrew bolts, the fixing both parts of a support to each other. In this case there can be a loss of tightness and the support will leak. |
| 3. Using a screw-driver edge as the lever, remove a bracket of fastening of a dustproof cover of the piston, then, being careful, remove a dustproof cover. |
| 4. Using a clip, fix one of pistons in a support. Giving air under low pressure through an opening for a brake hose, squeeze out the piston from a support. Be careful not to drop the piston as in this case most likely, it will be damaged. |
| 5. Using wooden whetstone, close an opening in a support. Remove the clip fixing the piston in a support and, using compressed air under low pressure, squeeze out the second piston from a support. |
| 6. Using the plastic or wooden tool, being careful, take sealing rings from flutes in the support cylinder. |
| 7. Check a condition of pistons and cylinders. In the presence of scratches, рисок, wear or pointed corrosion it is necessary to replace the piston and the cylinder, and it means that it is necessary to replace a support assembled. |
| 8. Check a condition of all details of a support and replace worn out or damaged. Irrespective of a state replace all rubber consolidations. |
| 9. Wash out all details in methyl alcohol or pure brake fluid and wipe them. For a clearing of tubes and openings use compressed air. |
| 10. Dip pistons and new sealing rings of pistons into brake fluid and apply a thin film of brake fluid on openings for pistons in a support. |
| 11. Establish sealing rings in openings of cylinders of a support. |
| 12. Install dustproof covers on pistons so that the internal diameter of a cover was included into a piston flute. Being careful and turning, insert the piston into a support. |
| 13. Insert an external edge of a dustproof cover into a support before its fixing. Fix a dustproof cover by a bracket. |
