Check Brake Forces Of Service Brake - Ar42.10-D-5000TS
Model 907 (except 907.8)
| Risk of death caused by limbs being caught or crushed by rotating parts when performing tests on the brake test stand | Never leave the vehicle unattended on the rollers except in an emergency. Ensure that no one is under the vehicle or near rotating parts during testing. In case of emergency, use the EMERGENCY OFF switch to shut down test stand. | AS42.00-Z-0001-01A | |

| 3 | Gradually apply specified test forces to the brake pedal, and compare the brake force reached on each axle against the reference values. | Reference values must be reached. Otherwise, the specifications for the legally prescribed minimum deceleration will not be met. Model 907 (except 907.8), Reference values for pedal force in accordance with manufacturer's specifications reference value method If reference values are not achieved, ↓ determine causes and rectify. |
