Replacement For A Reliable ACT 7.5 KS Brake Actuator

Updated 07/09/2024 | Published 09/16/2021

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.
