Wheel brakes

The following information regarding brake adjustment applies for all

models with the exception of Premium vehicles.

The wheel brakes that have been used are drum brakes that do not

automatically adjust. They have an automatic reverse that is sensitive

to the course you drive. The linings of the wheel brakes are wear

and tear parts; therefore, they must be checked every 5,000 km or

at least once every year. One sure sign of strong brake lining wear

is described in the aforementioned check for the overrunning equip-

ment: if the safety clutch can be pushed in more than approx. 45 mm.

Automatic Brake Adjustment (Premium)

All Premium models have an automatic brake adjustment that

independently compensates for wear in the brake lining.

• Regular adjustment of the brakes is not

necessary.

• Brake adjustment is automatically deactivated when driving in

reverse.

Despite this brake adjustment, the brake linings are generally wear

and tear parts. Therefore, their condition must be checked every

5,000 km, but no later than once every year. Visual inspection is

carried out through the small inspection holes on the rear of the

wheel brakes.

Please go to an authorised specialist if, when checking the over-

running brakes, the drawbar can be pushed in more than 60 mm.

It is mandatory that the brake pads (exception: Pre-

mium models) are regularly adjusted by an autho-

rised specialist to compensate for wear in the brake

lining and minimise brake pedal travel on the wheel

brakes and, therefore, the overrun coupling, keeping

it as consistent as possible. All models, including the

Premium model, must undergo an initial inspection

by an authorised specialist after the rst 500 km (see

also 12.3 Brakes).

• When driving downhill on a mountain pass, check

to ensure that the brakes are cooled suciently.

• Put the base vehicle into a lower gear and drive

downhill at slow speed.

• Stretch the trailer combination as often as possible

to avoid continuous bung by the caravan.

• Always make use of parking areas and passing points

to give the brakes a chance to cool o.

Please read the separately enclosed operating manu-

al of the axle/brake manufacturer (Knott).
