I can help you determine what hubs and rotors will work to as replacements on your trailer, but I will need a bit more information. Additionally, it is best to replace the hubs and rotors for both sides of the trailer to know that you are getting the best brake power equally on both sides of the trailer.
First I will need to know the outer diameter of the existing rotor on your trailer. This information will help me determine the size replacement rotor and will in part help me determine what your trailer's axle is rated for. You mentioned there are not identification numbers on the trailer, but if there is a label on the axle that lists the axle's capacity, that information will be very helpful.
I will also need to know the inner and outer bearings used in the hub. You can check the bearings for part numbers stamped into them. If there is no legible part number on the bearing, you can also use a digital caliper, like # PTW80157, to measure the inner diameter of the bearings to 3 decimal places. If the bearings are not available to measure, you can also measure the inner and out bearing seats on the spindle. I've attached a photo that shows where to measure the spindle to find the bearing seat measurements. The bearings will help me determine what size hub is needed for your trailer and further help me determine the axle's capacity.
To further help me find the correct hub for your trailer, I will need to know the wheel bolt pattern of the existing hub. I've attached a help article on determining the wheel bolt pattern for you.
If you can let me know the rotor diameter, bearings/bearing measurements, and the hub's wheel bolt pattern, I will be happy to determine the correct replacement hubs and rotors for you.
