Service brakes are wet multi---disc brakes fitted in the rear
axle housing. Service brakes are controlled hydraulically by
means of the brake pedals. When the brake pedals are
pressed, the 4WD engages causing brake action also on the
front wheels.
Brake pedals can be used separately as steering brakes or
they can be latched together.
Parking brake hand lever acts mechanically on the foot
brakes (not HiTech---models). The brakes can be adjusted
by means of the adjusting nuts. In HiTech---models the
parking brake is controlled electro---hydraulically (see
pages 521/2---3).
As an optional equipment, the brake valve for a trailer is
available. Also pressure---air brakes for trailer is available
as an option.
