Question

Question:

Hi, I am looking for a kit to put disc brakes on my trailer. 14 inch wheels, 5x4.5 lugs, and the backing plate holes are on 2-13/16 centers. Looking for surge assembly for 2-5/16 ball, as well as all stainless set for one axle.

To add hydraulic disc brakes to your trailer you will need a few parts.

For a hub and rotor assembly I recommend the Kodiak Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Dacromet - 3,500 lbs # K2HR35D which will allow you to use your 14" wheels and bolts to your 4 bolt brake flange. You will need to confirm that your spindles use inner bearing # L68149 and outer bearing # L44649, but since all of our 14" wheel options use those bearings this should be the kit you need.

You will need inner bearing # L68149, outer bearing # L44649, and grease seal # RG06-050. The required races are included with the Kodiak Kit.

For a 2 5/16" surge assembly I recommend the Demco Hydraulic Brake Actuator w Drop and Electric Lockout # DM8104311.

Lastly you will need brakes lines, but we do not offer stainless steel brake lines. I recommend the Kodiak Hydraulic Brake Line Kit - Single Axle - 18' # 18SI-BLKIT or the HydraStar Hydraulic Brake Line Kit # HS496-251 if your trailer is longer that 18'.

I included videos for all of the parts mentioned and a helpful article that goes over adding hydraulic disc brakes to a trailer for you to take a look at.

After speaking with EZ Loader what you have on your trailer is a 3,700 lb axle. From what they said the axle was upgraded even though your overall trailer capacity is 3,100 lbs. Although this uses the same #L44649 outer and #L68149 inner bearings,…

I did some looking and found that the 46210 and 46845 hubs you currently have use the same #L68149 inner bearing and #L44649 outer bearing. However, as we do not carry the Tie Down Engineering Vortex hubs, I cannot say what all will fit them,…
