Expert Reply:

I'd be happy to help you find out which hydraulic brakes are going to work on your 1997 Jayco Eagle 12 UD ST pop-up, but there isn't a database for me to find any of this information so you're going to need to do a little work here.

The easiest way is look for an axle tag on the center of the axle beam, but with the age of your trailer it may not be there. If it's not there then look for a part number stamped on the front of the hub, I can use that to figure out which size brakes you use.

If all else fails you'll need to remove one hub and look for which bearings it uses by measuring the spindle with digital calipers # PTW80157 in the spots shown in the diagram below.

Your trailer uses either # 23-398-399 if it's a 2k or 2,200lb axle, or # AKUBRK-35 if you have a 3,500lb axle instead.
