Check

Turn off edge of a cover of the wheel cylinder and examine it from within. At detection of any traces indicating infiltration of liquid under a dustproof cover, replace the cylinder.

1. Remove drums and blocks (see subsection 11.13.1, subsection 11.13.2).

2. Substitute the pallet, unscrew the union and muffle a tube and an opening in the cylinder.

3. Disconnect a tube, turn off fastening bolts.

5. Installation is carried out upside-down.

6. Tighten fastening bolts with m 18 N.' moment.

1. From the removed cylinder carefully remove dustproof covers and get pistons.

2. Check a condition of details, existence on the cylinder of scratches and traces of corrosion.

3. Check a gap between the piston and the cylinder. If the gap exceeds 0,15 mm, then assembled replace the cylinder.

4. At assembly dress on pistons new a sealant by means of MB990621-01 cone, previously having greased a sealant and a cone with lubricant from a remkomplekt or brake fluid.
