In the new condition the following pressure values may be slightly higher in order to adjust the relaxation expected in operation.

General specifications for brake system

Service brakes

Dual circuit, brake system with ABS, working purely pneumatically, or with an electropneumatically overlaid circuit

Parking brake and auxiliary brake

Spring-loaded actuator

Permanent brake

Engine brake (Turbobrake or exhaust flap and constant throttle), retarder

Pressure regulator with a constant pressure system:
Shutoff pressure
Cut-in pressure
Pressure regulator with pressure control system:
Shutoff pressure
Cut-in pressure


12 (-0.3/+0.6) bar
 9.8 bar

10 (-0.2/+0.6) bar
 9.3 bar

Operating pressure of service brake (circuit 1 and 2) with constant pressure system

Operating pressure of parking brake, trailer brake and consumers (circuit 3 and 4)

8.5 (+0.2/-0.5) bar

Four-circuit protection valve:
Opening pressure, circuits 1 and 2 (connections 21, 22)
Closing pressure, circuits 1 and 2 (connections 21, 22)
Opening pressure, circuits 3 and 4 (connections 23, 24, 25, 26, 27, 28)
Closing pressure, circuits 3 and 4 (connections 23, 24, 25, 26, 27, 28)

Design pressure of towing vehicle with constant pressure system
Design pressure of towing vehicle with pressure control system
Vehicles with relay valves on leading axle:
On these vehicles, the design pressure for the leading axle corresponds to the bellows pressure at the leading axle that can be achieved with permissible axle load, divided by 1.5 (pressure ratio of pressure reduction valve).
