Installing the 67.7820.9518 tool for adjusting the rear brake pressure regulator
1 – pressure regulator drive lever bracket; 2 – rear wheel pressure regulator drive lever; 3 – device 67.7820.9518; 4 - connecting rod of pressure regulator drive lever with rear axle beam bracket
1. If the bolts securing the rear brake pressure regulator have loosened, adjust its position. To do this, lift the rear axle of the car and loosen bolts 1 and 2 (see fig. Diagram of installation of the rear brake pressure regulator and its adjustment) so that the regulator can be easily rotated relative to the mounting bracket.
2. Disconnect lever 4 from rod 7 and attach tool 67.7820.9518 to its end (see Fig. Installing tool 67.7820.9518 for adjusting the rear brake pressure regulator).
3. Direct the rod of the device upwards until it stops against the body. This sets the distance of 140+5 mm between the end of the lever 4 (see fig. Diagram of installation of the rear brake pressure regulator and its adjustment) and the body side member.
4. Lift the protective rubber cap 3 and, by turning the pressure regulator on the bolts, achieve light contact of the lever with the piston 6.
5. While holding the pressure regulator in this position, tighten bolts 1 and 2 until they stop, then coat axle 8 and the protruding part of the piston with DT-1 grease.
6. Replace the rubber cap.
7. Remove tool 67.7820.9518 and connect the end of the lever to rod 7.
