No worries. We can help you pick out the correct type and size of replacement brakes you need for your trailer. We carry electric and hydraulic drum brakes as well as disc brakes, all shown on the linked page.

Just click on your brake type, such as electric drum brakes, like the part # AKEBRK-35-SA that you referenced, which is a left-and-right set of 10 x 2-1/4-inch self-adjusting electric brakes rated for a 3500-lb axle. You can measure your hubs' depth and diameter to confirm the size you need, see photo please. These brakes work with 13-, 14- or 15-inch wheels.

The things you need to match up are the brakes' weight capacity which must match the axle's and their mounting bolt pattern. Most 10 x 2-1/4-inch brakes use a 4-bolt mounting pattern and an axle's weight rating can usually be found on a plate or sticker on the axle itself.
