* increased Boost setting may be needed if trailer
brakes are worn, see Appendix A or a dealer for brake
adjustment or repair.
NOTE:
1. Always warm the trailer's brakes before setting
the power. Warm trailer brakes tend to be more
responsive than cold brakes. To warm trailer
brakes, drive a short distance (1/4 mile) at 45 MPH
with manual lever engaged enough to cause trailer
braking at a low level.
2. WARNING The power should never be set high
enough to cause trailer brakes to lock up. Skidding
trailer wheels can cause loss of directional stability
of trailer and tow vehicle.
3. The power/Boost may need to be adjusted for
different load weights and road conditions.
4. Not all trailer brakes will lock up due to various
conditions. However, inability to lock up the
brakes generally indicates the need for an
inspection to determine the cause.
5. When the power is set correctly you should feel
unified braking between the trailer and tow vehicle.
