"Gazelle" Gas-2705>> Brake system>> Maintenance service and repair of brake systems>> Adjustment of a drive of a lay brake
If at car braking by a lay brake the lever 1 (fig. 8.7) see at the appendix to it of effort 600 Н (60 кгс) and is more fixed on extreme top teeths of sector it is necessary to make drive adjustment in a following order:
- To establish the drive lever in extreme bottom position;
- To remove заглушки 20 (fig. 8.6 see) in brake mechanisms of back wheels. Using a key-asterisk of 17 mm, to weaken on 1,0—1,5 turns a nut of fastening of the clown of the adjusting mechanism of one of brakes;
- To exclude a backlash between разжимным a link 11 and the lever 12 for what a special tubular key in the size of 9 mm to turn a bolt 25 clowns in a direction specified by an arrow until resistance to rotation which is connected with a release колодок (a start of motion колодок will be felt it is possible to define also through observation ports in a board);
- To tighten a nut of fastening of the clown the moment 24—35 Н·м (2,4 3,5 кгс·м) in position of the beginning of a release колодок. Thus by means of a key of 9 mm it is necessary to keep a bolt 25 clowns from turn;
- To adjust in a similar way position разжимного a link 11 in other brake mechanism;
- To establish заглушки in brake mechanisms;
- To check up presence of backlashes between tips of cables 5 (fig. 8.7 see) both 8 and hollows on the equalizer 9. Backlashes are eliminated by a tightening of nuts of fastening of cables on an arm 4. Adjustment should be made so that after adjustment the equalizer Would be on distance from a forward wall of an arm and perpendicularly longitudinal axis of the car.
At correctly adjusted drive of a lay brake the drive lever under effort 600 Н (60 кгс) should not move more, than on 15 teeths of the locking mechanism.
