Electric brakes
The brakes should be adjusted after installation and serviced as needed for the life of the
brake system components. To adjust the brakes, use a brake adjustment screw tool to turn the
adjustment gear on the inside of the assembly. Continue to turn the gear until the drum surrounding the
bare catches on the brake pads enough, so that the hub cannot be rotated by hand easily. Then reverse
the gear about 10 clicks. A properly adjusted brake should have a slight drag on the brake drum. It is
recommended to re-adjust the brakes whenever servicing the bearings (every 3000 miles).
Break –in period
The break-in period is required for the brakes to achieve full performance. This break-in
period applies for new axles and any time new brake shoes and/or magnets are installed as part of
regular maintenance.
Brakes can be seated by applying approximately 8-10 volts to the trailer brakes at an
initial speed of 35-40 mph while allowing the tow vehicle/trailer combination to slow down to 20-25
mph. Take care to not overheat the brakes; brake application should be conducted in one mile intervals.
You should feel a notable difference in the brake performance during this period. After 10-30
applications, the brake shoes will be fully cured from the heat and will develop close to 100% contact
with the brake drum. This break in period not only seats the brake shoes, but also seats the brakes
electromagnets.
Note: Brakes should be manually adjusted after the first 200-300 miles of operation and periodically
thereafter, normally 3000 miles intervals, when servicing the wheel bearings.
Use only genuine Axletek replacement brake parts when servicing your brakes. Smittybilt carries
complete brake assemblies only. For individual replacement parts contact your local Axletek dealer.
Note: It is advised that after any river crossings, driving thru deep mud, deep sand, or water etc., you
need to inspect/clean the brakes. If not cleaned out, mud can grind your brake shoes, drums and
magnets away very quickly. Clean and dry brake assemblies completely before re- assembly. Be sure re-
pack axle bearings each time you disassemble them.
Note: A brake controller must be used with electric brakes. Smittybilt recommends the Prodigy P3
electric brake controller, however there are many other great quality brake controllers on the market.
Choose one that best suits your needs and has the features desired for your type of towing.
