Just started our 2nd season with our Rockwood 2306. I've always felt like the trailer brakes were never quite strong enough, so I've slowly been increasing the setting on my brake controller since last season (Prodigy Primus IQ). I'm currently at 11 volts and the trailer brakes don't even seem close to locking up. I believe the controller adjustment only goes to 13 volts.
So... is it possible my trailer brakes need servicing? I've put probably 4000 miles on them and have never had them checked (shame on me, I know). Anything else I should look into? Should I try the max (13 volt) setting and see if they lock up then?
Assuming I need to adjust the brakes, is this something I can do myself? I'm pretty handy and do most of my car and truck service myself. Prodigy offers these seemingly simple instructions:
Brakes should be adjusted after the first 200 miles of operation when the brake shoes and drums have “seated” and at 3000 mile intervals, or as use and performance requires. The brakes should be adjusted in the following manner:
- Jack up trailer and secure on adequate capacity jack stands. Follow trailer manufacturers recommendations for lifting and supporting the unit. Check that the wheel and drum rotate freely.
- Remove the adjusting hole cover from the adjusting slot on the bottom of the 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.
- Then rotate the starwheel in the opposite direction until the wheel turns freely with a slight lining drag.
- Replace the adjusting hole cover and lower the wheel to the ground.
- Repeat the above procedure on all brakes.
