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.

Answer 1

No, they're different systems Brain. Any hub can be used for the Vault lubrication system so long as the hub bore matches the diameter of the cap. An Easy Grease Hub Assembly like item #AKIHUB-545-35-G-EZ-K has an open ended grease cap to access…

Hey Kenny, most likely everything is totally fine. 2,400 miles shouldn't be much at all for the bearings in your Vaul hub. As long as you haven't seen any grease/oil leak out of the hub and they aren't getting overly hot I would say your…

Answer 3

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…

Answer 4

For a standard grease cap close to your original's 1.975-inch diameter you can use part #F001610 which is 1.960-inches. If your hubs are not threaded, then for a Bearing Buddy protector you can use stainless steel part #BB1968SS or chrome-plated…

Answer 6

It's most likely a blown fuse under the hood of your 2016 Ford F-350 that's not allowing the charge circuit of your 7-way to be active. That would be what you should check first. Next make sure there's no corrosion on the 12 volt pin of…

We don't have any replacement parts available to fix your Reliable ACT 7.5k actuator but if you've got drum brakes you can use the Titan Brake Actuator with Manual Lockout - Bolt On - Drum - 2" Ball - 7,500 lbs Item #T63FR which comes…

Answer 8

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…

Answer 9

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…

Answer 11

While I do have a potential solution for you, we do not carry a kit that would allow you to to use a TDE brakeaway on a Dexter LP75 actuator. TDE is no longer is business, so finding compatible parts may be near impossible. We do have a replacement…

Answer 12

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…
