Recommended Replacement Solution for Atwood 82543 Hydraulic Actuator


I had purchased these brakes for a boat trailer and installed on dual axles. I am having issues with the brakes locking up and not releasing. I bled the brake lines, and rebuilt the Atwood 82543 brake actuator thinking that the issue was stemming from the master cylinder not releasing. I am continuing to have the same issues. After a 40-50 mile trip, the brakes will lock up. I end up just opening the bleeder valve to release the pressure, then I am good for another 40 or so miles. Would you have an idea of what may be going on? Should I replace the actuator? Or is there anything else I should be looking at? Thank you

Considering that you've flushed the brake lines, we can rule out a clog causing this issue and because you've already replaced the master cylinder, it's not outside of the realm of possibilities that the actuator just needs to be replaced. You could check the actuator bolt/shock on the coupler mechanism as that might be what's sticking and creating this issue, but as you've seen, replacement parts for Atwood couplers are difficult to come by.

For this reason, I do recommend simply replacing your old Atwood 82543 with the Demco Hydraulic Brake Actuator - Drum - Zinc - 2" Ball - 7,000 lbs # DM72VR, which will give you a completely new system with your new # AKFBBRK-35-D.
