Division 1.4 Parking braking performance and efficiencyX1
United Kingdom
| 1.4.1. Performance | Apply the brake during a test on a brake tester. | Brake inoperative on one side or, in the case of testing on the road, the vehicle deviates excessively from a straight line. | X | ||
| Less than 50 % of the braking effort values as referred to in point 1.4.2 reached in relation to the vehicle mass during testing. | X |
| Item | Method | Reasons for failure | Assessment of deficiencies | ||
|---|---|---|---|---|---|
| Minor | Major | Dangerous | |||
| 1.4.2. Efficiency | Test with a brake tester. If not possible, then by a road test using either an indicating or deceleration recording instrument or with the vehicle on a slope of known gradient. | Does not give, for all vehicles, a braking ratio of at least 16 % in relation to the maximum authorized mass or, for motor vehicles, of at least 12 % in relation to the maximum authorised combination mass of the vehicle, whichever is the greater. | X | ||
| Less than 50 % of the above braking effort values reached. | X | ||||
| 1.5. Endurance braking system performance | Visual inspection and, where possible, test whether the system functions. | (a) No gradual variation of efficiency (not applicable to exhaust brake systems). | X | ||
| (b) System not functioning. | X | ||||
| 1.6. Anti-lock braking system (ABS) | Visual inspection and inspection of warning device and/or using electronic vehicle interface. | (a) Warning device malfunctioning. | X | ||
| (b) Warning device shows system malfunction. | X | ||||
| (c) Wheel speed sensors missing or damaged. | X | ||||
| (d) Wirings damaged. | X | ||||
| (e) Other components missing or damaged. | X | ||||
| (f) System indicates failure via the electronic vehicle interface. | X | ||||

| 1.7. Electronic brake system (EBS) | Visual inspection and inspection of warning device and/or using electronic vehicle interface. | (a) Warning device malfunctioning. | X | ||
| (b) Warning device shows system malfunction. | X | ||||
| (c) System indicates failure via the electronic vehicle interface. | X | ||||
| 1.8. Brake fluid | Visual inspection | Brake fluid contaminated or sedimented. | X | ||
| Imminent risk of failure. | X | ||||
