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.

  • Torrance Robinson

    Do you have part number 85841 and 84258 I stock? Price?

  • Don

    Price list. Where can I find on my Atwood master cylinder a serial number. All I see is 171
  • Johnny

    Why do I have a very noticeable clunk when I pull away from a stop.

  • David Lambin

    I have an Atwood I need to replace. P/N 85778, Max tongue load 900 lbs, SAE/GSA Class 4, Max trailer GVWR 6,000 lbs with 2" ball. What do you suggest? Seems every web site reference this disc brake actuator falls short of delivering.

    Thank you

    David
