Replacement For A Reliable ACT 7.5 KS Brake Actuator

Question

Question:

Hello there, I’m looking to replace the inner slide surge brake system for 2010 Trailmaster Vanguard single axle disc brake system? Need to replace this current oem part number ACT 7.5 Ks inner slide….would the Dexter 7.5 L inner slide single disc brake work ? I don’t think the large connecting pins would line up ? Photos of my existing inner slide are attached, thank you for the assistance,

At this time we do not carry a compatible inner member for your Reliable ACT 7.5 KS actuator so I recommend replacing it with the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout # DX89FR. This hydraulic actuator activates trailer's brakes when tow vehicle slows or stops and electric reverse lockout lets you back up without actuating trailer brakes.

So is it possible to swap the inner slides or not?

@Joey It's possible but you'd need to get the replacement from the manufacturer of the actuator. We unfortunately do not carry it so a total replacement with something like the # DX89FR is all we can offer at this time.

Hi Gary; I'm sorry we don't have a video installing the #DX64XR at this time but I did go pull the installation manual out of the box for you. You need to remove the inner member and then route the cable as seen in the instructions. Dexter…

I'm guessing it is approximately 3-3/8" across if you measured it. Unfortunately there are no options that will slide in because it won't line up correctly, and everything is designed to fit a 3" tongue so it is too wide to mount an…

The first thing that I would recommend checking are the ground connections for the trailer side connector and the lights. Poor ground connections are the most common culprit of trailer wiring issues. The lights will have either a ground wire or they…

Hello Jarrod, thanks for reaching out. The main difference between the Dexter #DX29FR and #DX89FR is how they attach to the trailer tongue. Each will fit a 3" wide tongue. The #DX29FR is designed to bolt onto the end of the tongue, whereas the…

For a replacement option I recommend the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout #DX89FR. Any swing-away actuators like your ACT-7.5K have been discontinued so this is the best solution. This has a 7,500 lb trailer capacity, is designed…

The foot plate of the Fulton #F1413200334 F2 Trailer Jack isn't removable. For a similar jack with a caster wheel, you'd want to go with #F1413050334. Because the caster wheel limits the weight capacity, the #F1413050334 jack has a 1600 lb…
