Introduction to Troubleshooting
Proper brake function is critical to the safe operation of any vehicle. If problems
are encountered with your trailer braking system, the following guide can be
used to nd the causes and remedies for some of the more common problems.
If you are unsure or unable to resolve the problem, please contact your nearest
repair facility for professional assistance.
Troubleshooting
Most electric brake malfunctions that cannot be corrected by either brake
adjustments or synchronization adjustments, can generally be traced to
electrical system failure. Voltmeters and ammeters are essential tools for proper
troubleshooting of electric brakes.
Mechanical causes are ordinarily obvious, i.e. bent or broken parts, worn out
linings or magnets, seized lever arms or shoes, scored drums, loose parts, etc.
Replace defective parts with genuine Dexter replacements.
Please consult the following troubleshooting charts to determine the causes and
solutions for common problems found in trailer braking systems.
CAUTION
Best braking performance is achieved with a controller setting that is
just short of wheel lock up or slide. Overly aggressive braking which
results in wheel lock up and sliding, can cause a dangerous loss of
control and result in personal injury or death.
