Road Test and Burnish Procedure
1. Check the brake system by measuring
amperage at each brake. Connect an
ammeter between either of the brake termi-
nals and the wire disconnect from that ter-
minal. The ammeter should read between
2.0–3.3 amps when brake is fully energized.
2. Make certain each brake is working
mechanically by lifting the axle, spinning the
wheel, and energizing the brake. The wheel
should come to a rapid halt.
3. Road check the brakes by making a few low
speed stops. Then burnish the brakes. A
fifty (50) stop minimum burnish at the fol-
lowing conditions is recommended.
