Maintenance (cont'd)
When disassembling the brakes for cleaning, make sure to:
1. Clean the backing plate, magnet arm, magnet and shoes.
2. Make sure all parts removed for cleaning are placed back into the same brake drum assembly.
3. Check for parts that have become loose or worn.
A. Service or replace loose or worn parts.
1. Use a straight edge to check the electromagnet surface for uneven wear (Fig. 4).
Note:
Figure 4 shows an electromagnet with little or no wear.
A. Surface of electromagnet should be completely flat.
B. If abnormal or uneven wear is indicated by pronounced gaps, replace the electromagnet.
2. If the magnet’s coil is exposed in any way, even if normal wear is evident, the magnets should be replaced immediately.
A. If the electromagnets are replaced, the drum armature surface should be refaced.
3. If an electromagnet is replaced on one side of an axle, LCI recommends replacing the electromagnet on the opposite brake
assembly. This will ensure an even braking capacity.
Clean and Inspect Brakes :
In the event the braking system encounters symptoms of improper application or failure, immediate inspection and service
MUST
be implemented. During normal use, servicing the braking system once a year is considered normal. Above normal use
will require servicing based on a 3,000-6,000 mile increment schedule. Change worn magnets and shoes as needed to maintain
maximum braking capability.
Magnets :
The LCI Electric Braking System uses high-quality electromagnets to actuate the brake shoes. These electromagnets provide
superior force and friction to safely, and effectively, stop the trailer. Inspect and service the electromagnets annually if the trailer
has seen normal use, more often if the trailer is used extensively. Inspect the electromagnets and do as follows:
