Procedure Note
1. Move electrical brake release tool to other
brake and connect.
2. Close the brake with the MX electrical brake
opening tool.
Move the toggle switch (6) on tool (1) to
OFF to open close the brake.
3. Adjust brake using procedure found in
previous section titled: ADJUST
EMERGENCY AND MAIN BRAKES.
4. After adjusting brake air gap, adjust brake
switch using procedure found in section
titled: ADJUST BRAKE SWITCH, FINE
ADJUSTMENT.
Adjust brake switch any time air gap is
changed.
5. After adjusting brake, reconnect main and
emergency brake coils to permanent
connections.
6. Check center nut (1), verifying that washer
under nut is loose and turns freely. If
washer does not turn freely, center nut (1)
is preventing brake from setting fully and
will reduce brake holding torque. Loosen
center nut (1). If center nut (1) is too loose,
manual release will not open brake. Tighten
center nut (1), but do not over tighten.
Washer must turn freely.
7. Test manual release operation by opening
brake using manual release. Verify brake
opens and car moves. If manual release
does not operate correctly, adjust manual
release according to procedure found in
section titled: ADJUST MANUAL BRAKE
RELEASE.
