To find the correct replacement brakes you will need to identify your axle capacity. Based on the specs of the trailer I'm sure you have a 3,500 lb or 4,400 lb axle. The Dexter Nev-R-Adjust Electric Trailer Brakes # K23-462-463-00 you looked at will work if you have the 4,400 lb axle. If you have a 3,500 lb axle you can use the # AKEBRK-35-SA or if you want to stick with Dexter the # 23-468-469. view full answer...
