This video shows you how to replace / change electric drum brake on a Sundowner horse trailer with two 5.2K lb. Dexter axles with 3000 lb. brake rating. The hub and drum brake combination will be replaced with new wheel bearing cones and cups along with grease seal. The brake shoes, not brake pads and magnets can be replace only, buy it’s much easier and cost the same just to change out whole assembly. Go ahead and repack the wheel bearings while you have the trailer brakes off. A viewer pointed out that I did not instruct to reconnect the wires. I used wire nuts and sealed them with hot glue.
