Video Transcript for Review of Demco Brake Actuator - Hydraulic Drum Brake Actuator 3 Inch Tongue - DM8101802

Hi everybody, Andy here with etrailer.com. And today we're gonna take a look at this Demco Hydraulic Drum Brake Actuator. Now this is a DA10 hydraulic actuator that will activate your trailer's brakes when your tow vehicle slows or stops. And as you probably know, when you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer towards the rear of your vehicle. With surge brake systems, the hydraulic actuator is triggered as your trailer moves forward once your tow vehicle starts to slow down. When this happens, this actuator contracts applying force to its master cylinder.

This in turn is going to supply the necessary hydraulic pressure to engage the brakes on your trailer. Now this is a bolt-on or weld-on insulation onto your straight three-inch wide trailer tongue. And I wanted to mention that if you're bolting this on, this does require 1/2 inch by 4 1/2 inch grade five bolts for bolt-on mounting. This is made here in the USA of a heavy duty steel construction with a prime finish and a gross towing weight capacity of 12,500 pounds and a maximum tongue weight of 1,250 pounds. Now this does feature the easy latch coupler mechanism for simple secure hookup and disconnect.

You're going to be able to hook up to your 2 5/16-inch hitch ball when this latch is in the closed position. And I want to give you a brief demonstration of that. So I have my 2 5/12-inch hitch ball here. And as you can see, I have my latch in the closed position. And so, as you can see, that's going to allow you to easily latch onto your hitch ball.

So you're just going to drop the coupler over that hitch ball and it's going to snap right in place. And then to disconnect, I'm just gonna lift this latch up and that's gonna allow for easy disconnection. Now this does feature a composite master cylinder and this is durable and efficient. It's glass reinforced nylon construction is going to resist rust and corrosion. And the large reservoir is going to provide increased capacity for brake fluid.

The large automotive style diaphragm cap creates a completely enclosed system that's going to help prevent the contamination of your brake fluid. Now this has an aceto liner here, copolymer lining that's going to give you that smooth operation as this actuator telescopes in and out. And this also features a breakaway cable. And this has a snap hook to ensure a secure connection to your breakaway lever, which is right here. And this is going to hook to your tow vehicle and prevent a trailer runaway situation. So if your trailer unhooks from your tow vehicle, this cable is going to pull that that lever and activate the master cylinder to apply the brakes to keep it from a runaway situation. Now I do wanna mention that because this actuator does not include a reverse lockout, it is recommended that you equip your trailer with free backing brakes so that you can drive in reverse without this actuator triggering your trailer brakes. Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
