Hi Kevin,

DC motors are sometimes just that simple.

One thing to look for while you have the brushes out, look for play in the shaft at the bearings. [up and down play]

If there is any play, this may be the cause of your brushes wearing out and at that point you should look for a replacement

or send your motor to a rebuilder.

Good Luck
Nick-

Kevin we just change them! But is a particular coach starts going through them more often than average than the other coaches then we look at why like Nick said! Very rarely a problem though, usually just worn from normal use! FWIW I HTH! ;D  BK  ;D
