| 1 | Determine the rear axle load and load the vehicle with weights if necessary | Fig 1 | |
| 2 | Connect pressure tester to test connection for unregulated pressure (1). | Pressure tester (hydraulic single/dual circuit brake systems) |
|
| 3 | Connect pressure tester to test connection for regulated rear-axle pressure (2). | Pressure tester (hydraulic single/dual circuit brake systems) |
|
| 4 | Use the brake pedal jack to apply pressure to the brake pedal, continuing until the pressure gauge indicates an entry pressure of 100 bar in the front-axle brake circuit. | Fig 2 | |
| 5 | Check the output pressure at the test connection, rear axle controlled pressure (2) or the brake caliper or wheel brake cylinder of the rear axle | *BE42.80-P-1001-01D | |

| Adjust | |||
| 6 | Adjusting exit pressure | Only carry out if the output pressure deviates from the adjustment pressure. Extending the threaded rod (4) increases the pressure Shortening the threaded rod (4) reduces the pressure. |

| 8 | Detach pressure tester | ||
| 9 | Bleed brake system | Only on vehicles without test connection for uncontrolled pressure (1) or test connection for rear axle controlled pressure (2). |
