Removal

Removal of the sensor of wear from an internal brake shoe on the DOHC models

Removal of dustproof caps on models with the ventilated disks

Removal of a support with an internal brake shoe on models with the ventilated disks

Removal of an internal block from the support piston on models with the ventilated disks

PERFORMANCE ORDER
1. In the presence remove the wear sensor from an internal brake shoe and disconnect the electric socket of the sensor located under a wheel arch (see rice. Removal of the sensor of wear from an internal brake shoe on the DOHC models).
2. Using a screw-driver edge as the lever, from the outer side of a support remove the fixing spring.
3. Remove dustproof caps from the internal ends of the directing bolts, unscrew the directing support bolts, lift a support with an internal block and, using a soft wire, tie up it to a forward rack (see rice. Removal of dustproof caps on models with the ventilated disks, Removal of a support with an internal brake shoe on models with the ventilated disks).
4. Remove an internal block from the piston of a support and an external block from the holder of a support (see rice. Removal of an internal block from the support piston on models with the ventilated disks).

Installation

Dredging arrangement on the support piston on models with the ventilated disks

Tightening of the directing support bolts on models with the ventilated disk

PERFORMANCE ORDER
1. Purify dust and dirt from a support, and a rust from edge of a brake disk. If blocks are suitable for further operation, clear them, using a wire brush and rags.
2. If new brake shoes are established, press the piston into a support a wooden core or the handle of the hammer. At the same time you watch that the piston did not warp also the surfaces of the piston and a boot were not damaged. At a piston vdviganiye brake fluid is forced out from the brake cylinder in a broad tank therefore constantly watch liquid level in a tank, and if necessary pump out its small amount from a tank.
3. Check that dredging on the piston of a support is located on a vertical axis. If necessary, turn the piston in the correct situation (see rice. A dredging arrangement on the support piston on models with the ventilated disks).
4. Apply a thin film of lubricant for the brake system on the surfaces of brake shoes interfaced to a support.
5. Establish an internal block on a support. At the same time the spring bracket has to be established in dredging of the piston.
Establish an external brake shoe.
Establish a support with an internal block on the holder of a support. Screw in directing bolts of a support and tighten them the required moment (see rice. Tightening of the directing support bolts on models with the ventilated disk).
Establish dustproof caps on the directing support bolts.
Establish the fixing spring on a support, at the same time the ends of a spring have to settle down in support openings.
In the presence install the new sensor of wear on an internal brake shoe.
Similarly replace brake shoes on the second wheel.
Establish wheels and lower the car on the earth. Tighten bolts of fastening of a wheel the required moment.
Several times press a brake pedal that brake shoes nestled on a brake disk.
Check the level of brake fluid in a tank.
After installation of new brake shoes avoid sharp braking during the first 160 km of a run of the car.
