Adjust | |||
1 | The clearance adjustment of the push rod (A) must be carried out with the pedals support and the brake pedal valve (7) installed on vehicle and the pneumatic piping securely connected | The pneumatic system will have to be pressurized to the specified service pressure (vehicle in driving condition). | |
2 | Move the push rod bellows (3) apart | ||
3 | Loosen the push rod adjustment nut (2) and manually check the clearance of the pedal valve push rod (1) | The clearance of the brake pedal valve push rod (1) can be perceived by moving the push rod laterally with the fingers tip. | |
4 | Place the brake pedal (5) in rest position | ||
5 | Insert the feller gauge blade between the brake pedal stop (4) and the brake pedal (5) | .Feeler gauge blade for clearance adjustment (A) of the brake pedal valve actuation rod | |
6 | Adjust the brake valve push rod (1) up to there is no clearance | ||
7 | Tighten the push rod nut (2) | .Rod regulation nut | |
| Check | ||
8 | Actuate the brake pedal (5) several times | ||
9 | Place a 0,70 mm feeler gauge blade on the brake pedal stop (4) | With the feeler gauge blade placed on the stop, there should have no clearance (A) of the push rod. | |
10 | Check the push rod clearance (A) again, by moving the brake valve push rod (1) laterally with the fingers tip | Without the feeler gauge blade, if the brake valve push rod (1) is correctly adjusted, a little clearance (arrow) between the brake pedal stop (4) and the brake pedal (5) is noticeable by actuating the brake pedal (5). | |
11 | Check if the cotter pin of the push rod is correctly installed | ||
12 | Fit the push rod protective bellows (3) |
