When carrying out the brake test while driving, ensure that this is done in accordance with 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.

In event of braking deceleration fluctuations or a pulsating brake pedal,

determine cause and correct.

After obtaining special order.

In event of any difference in service brake performance on wheels on a single axle.

Check and correct tire pressure.

After obtaining special order.

If the service brake performance difference remains even after repeat brake test on the wheels on a single axle.

determine cause and correct.

After obtaining special order.

If locking limit is not reached:

Check whether the brake values still comply with the legal regulations.

After obtaining special order.

If the specified minimum requirements and tolerance limits for the brake system are not fulfilled in accordance with the country-specific legislation.

determine cause and correct.

After obtaining special order.

2

Check braking characteristics of parking brake when driving at  4 km/h ( 2.5 mph).


When carrying out the brake test while driving, ensure that this is done in accordance with 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 at a speed of   4 km/h ( 2.5 mph).

If locking limit is not reached:

Check whether the brake values still comply with the legal regulations.

After obtaining special order.

If the specified minimum requirements and tolerance limits for the brake system are not fulfilled in accordance with the country-specific legislation.

determine cause and correct.

After obtaining special order.

Brake test on roller brake test stand

Danger

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

3.1

Set hydraulic valve or electrical selection switch in engine compartment to "TEST" position.

Model 124.226/230/290/330/333/393

Model 197

Model 197.3/4

AR54.30-P-1000-02QQ


Do not switch off ESP® using the ESP® Sport OFF button on the center console.
Otherwise, an active intervention by the ESP® brake system may lead to measurement errors.

4

Perform gear ratio change from "High" to "Low".

Model 164, 166
with code 430 (Offroad package)
Model 463
as of model year 2019
with code ZB4 (Off-Road package)

To do so, press the "Low Range" button on the lower control panel and drive for 20 to 50 meters to shift from the "High" on-road ratio into the "Low" step-down ratio.
If "Sport" transmission mode has been activated, it is not possible to shift to the "Low" step-down ratio.

5

Move vehicle with front axle onto roller brake test stand.

WS42.00-P-0006B

6

Move automatic transmission to selector lever position "N" or shift manual transmission to neutral.

7

Determine and document the braking characteristics and brake values of the front axle.


On all-wheel drive vehicles, the speed of the roller brake test stand rollers may 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.
The drive train and brake system can otherwise be damaged.

Press brake pedal uniformly. Document maximum values before wheels lock.

8

Move rear axle of vehicle into roller brake test stand.

WS42.00-P-0006B

9

Move automatic transmission to selector lever position "N" or shift manual transmission to neutral.

10

Determine and document braking characteristics and brake values of rear axle.


On all-wheel drive vehicles, the speed of the roller brake test stand rollers may 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.
The drive train and brake system can otherwise be damaged.

Press brake pedal uniformly. Document maximum values before wheels lock.

11.1

Determine and document braking response, brake values and actuating travel of parking brake.

Vehicles with mechanically actuated parking brake.

Operate parking brake uniformly. Document the number of notches and the maximum values prior to the wheels locking up.

11.2

Determine and document braking characteristics and brake values for electric parking brake.

Model 197, 216, 221
Vehicles with electrically-operated parking brake.


On all-wheel drive vehicles, the speed of the roller brake test stand rollers may 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 press and hold.
Otherwise damage will occur.

Document maximum values before wheels lock.

11.3

Determine and document braking characteristics and brake values for electric parking brake.
