12 'heavy-duty electric brake
The magnets in the back panel have 2 wires that are directly connected to the trailer wiring. When energized, it magnetizes the brake magnet. The magnet is attracted to the surface of the drum. When it comes into contact with the area, friction causes it to rotate, move the actuating arm, and push the brake shoes out of the brake drum. These brake shoes have a special type of brake pad material that can resist the heat generated by friction. When the brake shoes are pressed against the inside of the brake drum, the brake shoes prevent the wheel hub from rotating, thereby preventing the wheel from rotating when in contact with the ground.

How to install electric brakes on a trailer
Firstly, you must remove the existing hub. Use a trailer as support. Remove the wheel. The dust cover is a metal cover located in the center of the wheel hub. Gently tap the screwdriver behind the "lip" and pry open the grease dust cover.
Under this cover, you will see a large nut and a cotter pin, or in some new models, there is a small metal "clamp" on the nut. Straighten the split pin and remove it, or use a small screwdriver to pry the small metal clip off the nut. It slammed into the nut and then bounced open.
The nut should be loose. Remove the nut, which will have a washer and an "external" bearing behind it. If you don't catch them, they will fall to the floor. Remove the nut and gently pull the entire wheel hub off the axle.

Next, find the correct backplane. These markings are left or right. If you sit in the driver's seat and look forward. The magnet is always at the bottom, and the 'arm' is always in front!
Install the lock washer under the nut and tighten it. Pay attention to the two green brake lines (in this photo, one end is inserted into the back panel '). On brake magnets, they are not positive or negative (they are not grounded), so it is not important which wire to connect.
Ensure that the outer bearing is lubricated, then place the hub, washer, and nut. When tightening, unscrew the nut and turn the hub. When rotating, tighten to approximately 40 foot-pounds (very tight to secure the bearings and hub).
After tightening the nut, stop rotating the drum and gently loosen the nut until it is tightened with your fingers.
Insert the cotter pin. If you don't do this, the nut will come off and you will loosen the tire! If the nut is tightened too tightly, it will burn out the wheel bearings! It must be fingers too tight!
If there is a metal "clamp" on the shaft nut, simply align the plane of the hole with the plane of the clamp and tighten it.
