22.10.2. Models with a motionless support with two pistons

Prevention

Do not unscrew bolts, the fixing both parts of a support to each other. In this case there can be a tightness loss, and the support will leak.

PERFORMANCE ORDER
1. Being careful, clear a support of brake dust and dirt.
2. Note an arrangement of pistons in a support in order that they could be established correctly on the places.
3. Take pistons from a support for what it is possible to use air under the low pressure given to the brake cylinder through an opening for a brake hose. At the same time instead of brake shoes establish wooden whetstone. Remove dustproof covers from pistons.
4. Using the small screw-driver, take sealing rings from flutes in support openings.
5. Wash out all details in methyl alcohol or pure brake fluid and wipe them. For a clearing of tubes and openings use compressed air.
6. Check a condition of all details of a support and replace the worn-out or damaged details.
7. Pay special attention to the cylinder and the piston. 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. Irrespective of a state, replace all rubber consolidations.
9. At installation check that all details pure and dry and that each piston is installed in the opening.
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 support openings.
12. Install dustproof covers on pistons so that the internal diameter of a cover was included into a piston flute.
13. Install a dustproof cover on the piston so that the internal diameter of a cover was included into a piston flute. Being careful and turning, insert the piston into a support and one-times but insert an external edge of a dustproof cover into a support before its fixing.
14. Similarly install the second piston in a support.

Installation

PERFORMANCE ORDER
1. Using the corresponding tap, clear a carving in an opening of the directing finger.
2. Screw a support on the connecting coupling of a brake hose.
3. On models with a mobile support with one piston establish a support on the holder of a support and screw in a new top bolt, the fixing directing finger. Tighten a bolt of fastening of the directing finger the required moment. At the same time, using a thin wrench, hold the directing finger from a provorachivaniye. Do not damage a protective cover of the directing finger.
4. On models with a motionless support with two pistons establish a support into place and fix it by new bolts, having tightened them the required moment.
5. On all models tighten a connector the ny coupling of a brake hose to a support. Remove the clip pressing a brake tube.
6. Establish brake shoes and remove air from the hydraulic brake system. If were all precautions are undertaken during the work with the hydraulic brake system, so it is necessary to pump over only the corresponding forward brake.
7. Establish a wheel, then lower the car on lands and tighten bolts of fastening of a wheel the required moment. Check the level of brake fluid.
