Hi Brian,

If you have a boat trailer with a 7,000 lb single axle you wouldn't have 10 inch brakes, they would be larger as 10 inch brakes are for 3,500 lb axles. Since I'm not 100% sure what you have I can't directly answer your question, but I can tell you how to find the correct replacement. You will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them.

If you are unable to find them, you need to use a digital caliper and measure your spindle where the bearings ride, like in the diagram I added below. For example, if you had inner bearing L68149 (1.378" inner diameter) and outer bearing L44649 (1.063" inner diameter) you would use the DeeMaxx Disc Brake Kit - 10" Hub/Rotor - 5 on 4-1/2 - Maxx Coating - 3,500 lbs # DE66YR.

I have added a link below to our entire selection of disc brakes which you can filter through, or if you let me know what your bearing numbers are I can help you find the right kit.

Kyle Sorry left the critical word. 7000lb actuator is on it. UFp a-70. Can’t seem to find a replacement. I believe it is not working. Is there a replacement for it or a rebuild kit? It is a shorlandr single axle disc brake. 2006

@BrianM Ok, that makes sense, and while there isn't a rebuild kit, what you can do is just replace it with the Dexter DX7.5L A-60 Brake Actuator # DX89FR. This is for disc brakes, couples to a 2" hitch ball, and bolts onto a 3" wide trailer tongue.
