For a 7,000 pound Dexter Never Lube axle with 8 on 6-1/2 inch bolt pattern and 9/16 inch wheel studs you will not be able to go with disc brakes on the existing axle. The Problem you will run into is that the center of the hub on your existing brake drum hubs will not work with the slip over disc. Machining the drum off still would not allow the slip over disc to fit correctly. In this case you will need to go with drum brakes like you already have or special order axles that are outfitted with standard wheel bearings. Machining the drum off of your existing hub may also weaken the hub and reduce the capacity, or cause the casting to crack, creating a very dangerous situation.

If you decide to change out the axles, my recommendation would be to go with a disc brake kit with hub and rotor, like # K2HR79E. Make sure the axle you order has a 5-Bolt brake flange, and uses a bearing kit with 14125A outer and 25580 inner Bearings and 10-36 Seal, # BK3-200.

Once you have selected the disc brake setup you will need some other parts. Since you already are set up for using a brake controller, I would recommend the electric over hydraulic braking system, # T4813102. You will also need the Gel Cell Breakaway Kit for Titan BrakeRite Systems, # T4822100.

Since the Prodigy brake controller is not compatible with electric over hydraulic systems you will need to upgrade the brake controller. I would go with the P3 brake controller, # 90195, which is compatible with these actuators. You can just unplug the wiring from your Prodigy and plug it right into the P3 and it will be ready to setup.

Finally, you will need a brake line kit to complete the installation on the trailer. The Titan Hydraulic Brake Lines and Fittings for Tandem-Axle Trailers, # T4830000, would be correct for two axles with brakes. If you will only be putting brakes on one axle the Titan Hydraulic Brake Lines and Fittings for Single-Axle Trailers, # T4829900, would be the parts needed.
