Titan Surge Brake Actuating Coupler to Replace Atwood Coupler

Question

Question:

Im looking to replace my atwood surge brake model #85091 with the Titan T4339720. Are the brake line fittings the same? If I purchase the titan T43329007K can I add the T4748800 electric reverse lockout solenoid?

The Titan Zinc-Plated Brake Actuator - Drum - Multi-Fit Ball - Bolt On - 7K # T43397007K is a great option for the Atwood coupler replacement. This does not include the electric lockout solenoid # T4748800. The brake line fittings will be the same.

The Dexter DX7.5 Drop-N-Go Brake Actuator - 2" Ball - Zinc Plated - 7,500 lbs # 099-175-00 is also a great replacement option, and you can add the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 to this actuator as well. I recommend also getting the Solenoid Shield # T4835800183 if you add that solenoid to protect it.

Answer 7

Your Atwood brake actuating coupler should not have started leaking brake fluid based on your manual lockout being engaged, so that is most likely not the issue. The only issue from leaving that lockout engaged should be the lack of trailer brakes,…
