Recommended Electric Over Hydraulic System For Disc Brakes On Triple Axle Trailer With 7K Axles  

Question:

Hello, I have a triple 7k axle trailer with electric brakes and I seem to always be replacing a wire do to a short, the spring and star wheel falls out, or a magnet goes haywire. I run a a hot shot and put about 130k miles on a trailer in a year. Id like to know what it would cost to convert these dexter axles to eoh and disk brakes. They are 7k axles, 2x12 brakes and 8 on 6.5 Thank you

For your 7,000 lb axles, I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - E-Coat - 7,000 lbs # K2HR79E. This kit uses inner bearing # 25580 (inner diameter of 1.750 inches) and outer bearing # 02475 along with oil seal # RG06-070 which has an inner diameter of 2.250 and an outer diameter of 3.376 inches. You will want to double check these measurements on your spindle using a caliper like # PTW80157 to confirm a fit. I've attached an article to assist.

For your actuator and brake lines, I recommend the HydraStar Electric-Hydraulic Actuator w/ Line Kit for Disc Brakes - 1,600 psi # CAR-HBA16-2. You will need to add Hydraulic Line Kit, 3rd Axle - Drum and Disc # 9579-01 to this system. This will complete your system and give you an excellent system for your Dexter axles.
