Hey Desi! What kind of trailer do you have? To find the right replacement you will need to identify your axles. The best way to do this is by checking your axle tag. For example, if you have a 3,500 lb axle the etrailer Electric Trailer Brakes # AKEBRK-35-SA you were looking at will fit. Assuming you need a 5 on 4-1/2 bolt pattern you can use the # AKHD-545-35-K for a hub and drum assembly.
If you have a different axle capacity, or it isn't clear based on the tag, feel free to add your axle tag information in the comments below and I'll help you find the right replacement parts.
