Supplement: Brake System, Post 09/2007 Trucks
As of 09/2007, DFG/TFG 425-435 series trucks have been fitted with a new service brake system. In future, in
addition to the slow travel / brake pedal (29) an additional brake pedal (21) will be available.
The brake pedal (21) hydraulically actuates two drum brakes which are applied to the drive wheels. The drum
brakes are also applied to the slow travel / brake pedal. However, this is only designed as a crawl speed aid and
should not be used for normal braking purposes. Worn drum brakes are automatically adjusted in case of wear.
Operation
Braking:
- Take your foot off the accelerator pedal.
- Apply the brake pedal (21) to stop the truck
Crawl speed travel with the slow travel / brake pedal:
Sensitive application of the slow travel / brake pedal (29) allows for excellent shunting in confined areas and
rapid lifting at a slow travel speed.
- By applying the slow travel / brake pedal, the flow of power in the power shift gear can be reduced in
the first stage of the pedal stroke. This means that the motor speed and hence the lift speed can be
increased while shunting, without speeding up the truck.
- Further pressing on the pedal allows the truck to brake easily, e.g. during crawl speed operations.
