Ask the Experts about this Demco Accessories and Parts

Do you have a question about this Accessories and Part?

Are There Replacement Master Cylinders Available for Brake Actuators
Yes, there are replacement master cylinders for surge brake actuators like the Demco Actuator part # DM8203102 that you referenced. If this was the actuator that you have you would want the Replacement Master Cylinder # 5672. If you have a different actuator I attached a page that has all of the replacement master cylinders we offer.

Will the Demco Brake Actuator # DM8202022 Work with Disc Brakes on a Boat Trailer
The Demco Channel Only Trailer Actuator, part # DM8202022, was designed to be used with drum brake applications only. You could use this actuator with disc brakes, but you would have to replace the master cylinder in the actuator with the Demco disc brake master cylinder, part # 5672. To save yourself some time, work and money, I would recommend going with the Titan Adjustable-Channel Brake Actuator. Titan offers a bolt-on and weld-on version of this actuator. For the bolt-on actuator,...

Replacement Brake Actuating Coupler for Upgrade to Disc Brakes
The bolt hole dimensions of the Demco Brake Actuator # DM8669112 are 12-1/2 inches on center and 3 inches on center. I've attached a photo to assist. The Titan # T4747220 has mounting holes that are 3 inch on center so 2 of the 3 holes will align with your current coupler. Instead of changing out your entire coupler, you may want to simply change out your master cylinder on your Demco Actuator using the Replacement Master Cylinder for Demco Actuators - Disc Brakes # 5672.

Can Surge Coupler/Actuators Be Converted from Drum to Disc Brake Operation
Surge couplers for drum and disk brakes use different master cylinders that operate at different pressures, lower for drums and higher for discs. It is possible to swap out the master cylinder in a surge coupler to convert it from one type of operation to the other. Depending on the number of brake assemblies, trailer length, etc, larger brake lines are sometimes also called for with disc systems. It sounds like you have free-backing drum brakes like # 40715 on the trailer now, which...
