I can tell you how to determine the correct disc brakes, but we can't do anything with a trailer VIN. So you need to know your axle capacity, bearing numbers, wheel bolt pattern, and what brake flange you have.

For example, if you had 7,000 lb axles with a spindle that fit inner bearing 25580 and outer bearing 14125A, an 8 on 6-1/2" bolt pattern, and a 5-bolt brake flange you could use the DeeMaxx Disc Brakes # DE88YR.

If you aren't sure what bearings you have, 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. For example bearing 25580 has a 1.750" inner diameter and 14125A has a 1.250" inner diameter.

If you aren't sure of what your wheel bolt pattern is I have added a link below to a help article which shows you how to measure. I have also added a link to our entire selection of disc brakes once you find this info.
