Inspection, Service & Maintenance ! WARNING Broken or damaged fasteners or welds can cause injury or damage to trailer and contents. Inspect for, and repair all damaged parts at least once a year. TRAILER BRAKES - ELECTRIC 10.2.1.3 Brake Shoes and Drums Properly functioning brake shoes and drums are essential to ensure safety. You must have your dealer inspect these components at least once per year, or each 12,000 miles. Brake adjustment is not covered under the axle warranty. The brake shoes must be adjusted after the first 200 miles of use, and each 3,000 miles thereafter. Most axles are fitted with a brake mechanism that will automatically adjust the brake shoes when the trailer is “hard braked” from a rearward direction. Read your axle and brake manual to see how to adjust your brakes. If you do not have this manual, contact your dealer for assistance. 10.2.1.4 Manually Adjusting Brake Shoes Some braking systems are not automatically adjusted by hard stopping. These brakes require manual adjustment. The following steps apply to adjust most manually adjustable brakes. Read your axle and brake manual to see how to adjust your brakes. If you do not have this manual, contact your dealer for assistance. �� Jack up the trailer and secure it on adequate capacity jack stands. �� Be sure the wheel and brake drum rotate freely. �� Remove the adjusting-hole cover from the adjusting slot on the bottom of the 148 brake backing plate. �� With a screwdriver or standard adjusting tool, rotate the starwheel of the adjuster assembly to expand the brake shoes. Adjust the brake shoes out until the pressure of the linings against the drum makes the wheel very difficult to turn. Note: Your trailer maybe equipped with drop spindle axles. See axle manual for your axle type. You will need a modified adjusting tool for adjusting the brakes in these axles. With drop spindle axles, a modified adjusting tool with about an 80 degree angle should be used. �� Rotate the starwheel in the opposite direction until the wheel turns freely with a slight drag. �� Replace the adjusting-hole cover. �� Repeat the above procedure on all brakes. �� Lower the trailer to the ground. 10.2.1.5 Brakes, Electric Two different types of electric brakes may be present on the trailer: an emergency electric breakaway system, which acts only if the trailer comes loose from the hitch
