The service brake (pneumatic or hydraulic) is activated from the driver's cab by pressing the
tractor brake pedal. The task of the control valve (2) - figure ((3.4), (3.5) and (3.6) , is to
activate the trailer brakes simultaneously with the tractor brake applied. In addition, in the
event of an unforeseen disconnection of the hose between the trailer and the tractor, the
control valve automatically applies the machine's brake. The applied valve has a brake
release system used when the trailer is disconnected from the tractor, see figure (3.8). After
connecting the air line to the tractor, the release device automatically adjusts to the position
enabling normal operation of the brakes.

Three-band braking force regulator (2) - figure (3.8), adjusts braking force depending on the
setting. Switching to the appropriate operating mode is done manually by the machine
operator before starting the journey using the lever (4). Three work positions are available: A
- ‘No load’, B - ‘Half load’ and C - ‘Full load’.
