	General brake test (Only applies for countries without a specified brake test on the roller brake test stand)
1	Check braking behavior of service brake when driving	It must be ensured that the brake test when driving is performed as per the country-specific legislation and regulations. Otherwise, people may be injured or there may be damage to material and the environment! Press brake pedal uniformly. With braking deceleration fluctuations or pulsating brake pedal ↓ Determine and rectify cause subject to separate repair order. With a difference in service brake performance on wheels on a single axle ↓ Check/correct tire pressure subject to separate repair order. If the service brake performance difference remains even after repeat brake test on the wheels on a single axle. ↓ Determine and rectify cause subject to separate repair order. The locking limit was not reached. ↓ Subject to a separate repair order, check whether the brake values still comply with the legal regulations. The specified minimum requirements and tolerance limits for the brake system must be fulfilled on a vehicle-specific basis in accordance with the country-specific legislation. If this is not the case. ↓ Determine and rectify cause subject to separate repair order.
2	Check braking characteristics for parking brake when driving at ≤ 4 km/h (≤ 2.5 mph)	It must be ensured that the brake test when driving is performed as per the country-specific legislation and regulations. Otherwise, people may be injured or there may be damage to material and the environment! Electrically operated parking brakes are only active as from a speed of ≤ 4 km/h (≤ 2.5 mph). The locking limit was not reached. ↓ Subject to a separate repair order, check whether the brake values still comply with the legal regulations. The specified minimum requirements and tolerance limits for the brake system must be fulfilled on a vehicle-specific basis in accordance with the country-specific legislation. If this is not the case. ↓ Determine and rectify cause subject to separate repair order.

Between the tests, a waiting period of at least 15 s must be observed, during which the axle may not be driven by the roller brake test stand rollers! The drive train and brake system can otherwise be damaged. Press brake pedal uniformly. Document maximum values before wheels lock.
9	Move vehicle with rear axle into roller brake test stand
	000 588 05 21 00 Roller brake test stand		WS42.00-P-0006B
10	Move automatic transmission to selector lever position "N" or shift manual transmission to neutral
11	Determine and document braking response and brake values of rear axle	On all-wheel drive vehicles, the speed of the roller brake test stand rollers my be max. 5 km/h and may not last for longer than 15 s per test of one axle.

Between the tests, a waiting period of at least 15 s must be observed, during which the axle may not be driven by the roller brake test stand rollers! Before operating the electric parking brake, the rear-axle complete wheels must be driven by the roller brake test stand until the vehicle has detected the roller brake test stand so that application of the brake pads is then slowed down. Otherwise damage may occur. Briefly press switch of electric parking brake once, do not hold. Otherwise damage will occur. Document maximum values before wheels lock.

Between the tests, a waiting period of at least 15 s must be observed, during which the axle may not be driven by the roller brake test stand rollers! Before operating the electric parking brake, the rear-axle complete wheels must be driven by the roller brake test stand until the vehicle has detected the roller brake test stand so that application of the brake pads is then slowed down. Otherwise damage may occur. The electric parking brake brakes briefly and then changes to the roller brake test stand mode. After 3 s press the switch of the electric parking brake again briefly, the electric parking brake brakes with greater brake power.
