Replacement for Atwood 85736. As I understand this is no longer available, can you confirm what the equivalent replacement bolt on surge brake assembly would be

Expert Reply:

You are correct that the Atwood 85736 master cylinder cannot be replaced so you would need a new actuator, and the closest replacement for a drum brake actuator is from Demco:

- Demco Hydraulic Brake Actuator - Drum - Zinc - 2" Ball - 7,000 lbs # DM72VR

The # DM72VR bolts onto a 3" wide trailer tongue, and you'll simply need 2-1/2" x 4-1/2" Grade-5 bolts to do so. It accepts a 2" hitch ball, has a 7,000 lb capacity and is super easy to use. You just have to drop the coupler over your 2" hitch ball and it latches automatically.
