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.

I bought a lund boat 21ft. Has your double axle braking trailer. Can you explain how this system works. I have problems with trying to get it off my ball hitch. I have to disconnect my reviewer and pull out leaving it hanging until I can wiggle it loose. I pull up on the lever ???

I’m looking for part# 85837 master cylinder rebuild kit, can I also buy part# 23375 wheel cylinder repair kits for both left and right side. I believe these are for 10" Atwood uni-servo brakes.
This surge brake system is on a 1999 Jayco UDK12 pop-up camper.
Thanks for any information.
