Atwood Hydraulic Brake Actuator Parts List and Schematic
Atwood's Unique Design for Superior Braking
- Unique design creates more pressure on the brakes than in-line actuator systems.
- Parts interchangeability between 6K and 8K actuators.
- Lock-out feature allows use with standard hydraulic brakes for backing up. No need for specific free-backing brakes.
- Disc brake actuators available specifically for use with disc brake systems. Supplies, even more, fluid pressure to brakes than standard hydraulic.
- A breakaway device will set trailer brakes automatically should separation from tow ball occur.
