Question:

Hey I’ve got a tandem axle trailer with 8k Lippert Axles with 5/8” studs I was looking into converting it to electric over hyd disc brakes

Expert Reply:

I would be happy to recommend all of the parts you need for adding electric over hydraulic disc brakes to your tandem axle trailer with 8000lb Lippert axles.

All of the 8000lb disc brake rotors we offer use the inner bearing # 25580 and outer bearing # 02475, so you will want to make sure that your spindles use the same bearings. The easiest way to do this is by removing one of your hubs and looking for the bearing number stamped in the face of each bearing as shown in the included picture of the # L44649.

Out of the rotors we offer I recommend the Kodiak 13" Hub and Rotor - 8 on 6-1/2 - E-Coat - 5/8" Bolts - 7,000 lbs to 8,000 lbs # KHR13858E which have the same 5/8" wheel bolts as your current hubs. You will also need inner bearing # 25580, outer bearing # 02475, grease seal # RG06-070, and grease cap # KPCAP for each hub.

Moving on to the rotors you will need the Kodiak Disc Brake Caliper # KDBC250E, Mounting Bracket # KCMB137IE, and Brake Pads # K250CP.

Next you will need brake lines of which I recommend the HydraStar Hydraulic Brake Line Kit - Tandem Axle - 25' Long, 3/16" Main Line # HS496-252.

To finish off the conversion you will break away kit # 20400, and electric over hydraulic actuator # HBA16.

You will need to make sure that your current brake controller is compatible with electric over hydraulic brakes. If it is not I recommend taking a look at the Tekonsha Prodigy P3 # 90195.

I included videos for the products mentioned for you to take a look at.
