How to Select Replacement Surge Brake Coupler for Yarborough Tandem Trailer


I need a drum brake actuator for a old yarborough tandem axle boat trailer! What type of info do you need?


Expert Reply:

We have surge actuator couplers for drum-type brakes for both straight-tongue trailers and for a-frame trailers, for all three sizes of hitch ball and with or without a reverse lockout feature. We also have bolt-on and weld-on couplers. All such items are shown on the linked page and you can click on the filters to narrow the range of products shown to just those with your preferred characteristics.

You will want to select your actuator coupler based on the trailer's gross weight rating (GTW). This will ensure sufficient hydraulic pressure to deliver the braking force required for the trailer's weight.

For instance, for a weld-on a-frame coupler with manual lockout rated for 6K you can use Titan # T2492800 which has a multi-fit feature enabling it to work with all three sizes of hitch ball. Or for a bolt-on straight tongue 7K coupler for a 2-inch ball you can use Demco # DM72VR.
