1. Clean the outer surface of the caliper, make sure that foreign objects do not get into the opening of the hydraulic hose.
2. Clamp the caliper in a vise.
3. Remove the dust cap (ki) from the groove (OK) in the support.
4. Place a die in the jaws of the caliper, opposite the piston (her).
5. Use compressed air to blow out the piston through the brake fluid inlet (neither) out of the hole (uy). If there are two pistons, remove the first piston by blocking one with a ram. Use a rubber block, ram and G-clamp to close the open cylinder so that the remaining piston can be removed.
6. Remove seal (I) piston from hole (uy), be careful not to scratch the hole surface. Remove the dust cap (ki) with pistons.
7. Turn off the pumping union.
8. Clean all parts with methanol and dry them.
9. Examine the piston surface and bore for signs of corrosion and wear. If necessary, the caliper assembly should be replaced, however, if the surfaces being checked are in good condition, prepare a repair kit containing new seals. Also prepare the paste for the brake cylinder.
10. Apply the paste to the surface of the hole (uy) and piston (her).
11. Position the seal (I) piston in groove (kah) holes.
12. To install the piston, place the dust cap on the end of the piston, then place the piston against the caliper and pry the dust cap into the caliper groove with a screwdriver. Now press the piston into the bore until the dust cap snaps into place in the groove on the outer end of the piston.
13. Install a new rubber cap on the bleeder port. Apply paste to the threads, then screw the bleeder screw into the caliper.
14. On a Girling caliper, apply grease to the guide pins before installation.
15. On the Teves caliper, check the guide pin bushings (teflon), if necessary, replace them. Also check the rubber bushings.
