The axle capacity is usually stamped into the centerline of the axle or placed on an information sticker in that same location. With that being said, the axle capacity is not necessary needed if you can provide me with the inner and outter bearing numbers or the diameters of the spindle where they seat. This is the most important bit of information that is needed. Please keep in mind that I would also need to know what size wheels you have on your trailer.

Once you can provide me with this information I would be glad to recommend the parts you need to convert to disc brakes.

I spoke to my contact at Dexter Axle and they informed me that the AL-KO part "7230" is a 10" diameter drum that uses an L68149 inner and a L44649 outer bearing. Therefore, the inner bearing seat should have measured 1.378" not 1.375". In order to convert the hydraulic drum brakes you have on your trailer to hydraulic disc brakes you will need a disc brake assembly and a brake actuator rated for use with disc brakes. For this, I recommend the Kodiak Disc Brake Kit part # K2HR35D and the Dexter Brake Actuator part # 099-175-20. The dacromet finish on the brakes and zinc plating on the actuator will work well to resist both rust and corrosion on your boat trailer. I have attached a review video on each item for you as well.

Answer 1

Hey Robert. The side bolts with the grease fittings should be tight on the Dexter DX7.5 Drop-N-Go Brake Actuator item #099-175-20. They're not holding the actuator on but you don't want the nuts backing themselves off. What kind of trailer do…

Hey Patrick! Do you have drum brakes or disc brakes? Is the actuator 3-5/8" wide or is the channel tongue on your trailer that wide? I'm guessing you have a 3" wide channel tongue which is pretty standard. Do you need a coupler for a…

You can select your new hubs by matching up your axle weight rating, wheel bolt pattern and the bearings used in your current hubs. Based on my research your hubs are 10 x 2-1/4-inches, are from a 3500-lb axle and have the 5-on-4-1/2 bolt pattern. If…

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…
