Parts Needed to Add Electric-Over-Hydraulic EOH Brakes to a 14K Trailer

Question:

I am looking at converting my trailer axles from electric breaks to hydrolic disk breaks. The rim size is 16" and the bolt pattern is 8x6.5. I would like to know if you have any kits for this. The sticker on my axles says it is a Wheel and Rim Century from Corona, Ca with a serial number of 20548. I think it was made 1987 and has a gvwr of 14k lbs. Please let me know if you have something to convert these over to electric over hydrolic disk breaks And let me know if you need any more information Thanks

Thank you for the information and the pictures!

We have exactly what you need to change your current hub and drum assembly to an Electric-Over-Hydraulic (EOH) disc brake setup.

The most popular disc brake kit that we have to offer if the Kodiak Disc Brake Kit # K2HR712D which comes with a 13" rotor that has an 8 on 6-1/2" bolt pattern and is rated for 7,000 lbs. The dacromet finish on this kit gives it the best protection out there especially for freshwater and saltwater use. The rotor uses the same 25580 inner bearing and 14125A outer bearing that your current hub has. The grease seal has a 2.250" inner diameter which you will want to check to make is compatible with your spindle.

If you don't already have the line run for a hydraulic brake system then you can use part # 20TA-BLKIT for 20' of line or part # 24TA-BLKIT for 24' of line. I prefer the hose over the metal line because it means your brake lines are more flexible and will last longer.

The key component to an EOH system is the actuator. For your disc brakes you need one with a psi rating of at least 1,500. I recommend the popular HydraStar Electric Over Hydraulic Actuator # HBA16 which has a 1,600 psi rating.

To activate your trailer brakes in the case of an emergency you need a breakaway kit. The Hopkins Kit # 20099 is one of the best on the market due to the push button battery tester and the built-in charger.

On the vehicle side of things you need a brake controller to activate the trailer brakes. I recommend going with the Tekonsha Prodigy P3 # 90195 because it features an LCD screen that makes operation much easier than other controllers that require you to remember codes. This brake controller has been confirmed to work with the HydraStar actuator without a additional adapters.

If you let me know what the year/make/model of your vehicle is I can give you more specifics on installing the brake controller.

I have attached some installation and review videos on the products for you to check out as well.
