NOTE: There are four brushes in the motor.
The brushes will not wear at the same
rate. It is recommended that all four
brushes are inspected at the same
time.

not be possible to inspect all four
brushes while the motor is in the
vehicle. Refer to

of the brush to the top of the brush holder. If it is
even with or below the top of the brush holder then
the brushes should be removed and measured.
