Adding electric brakes to a Teardrop trailer is a relatively simple job. The supplied axle has no flanges to attach the brake plate assembly, so the simplest way to do the job is to buy a complete axle assembly from Princess Auto. You will have to move up to the 3500 lb axle which is slightly heavier, but obviously stronger. It has exactly the same mounting centres as the axle that came with your trailer. You will also need the stronger U bolt mounting kit. There is a left and right side to this assembly which is important to get right, otherwise not much you can do wrong. This axle assembly has 10 inch brake drums and works well with the 14 inch wheels. If you buy the axle assembly on sale it is a super bargain. Every flyer has a different axle on sale.
You will have to choose a brake controller for your car. I chose the progressive type and am very pleased with it, but they all stop you.
The smaller and lighter your car, the more you will benefit from the brakes. If you are driving a truck like Steve's, better to spend your money on some good wine. You don't need brakes.
Or you could ask us before we build it, and have it installed for you :-)
We have installed both electric and hydraulic. Happy trails.
