replace the starter
Its not worth replacing the starter motor brushes on any car. By the time the brushes are worn, there is probably other wear and tear to the bearings, the commutator, and the windings. Better to just replace the starter. Same deal with the brushes in an alternator.
the brushes, just replace the the whole starter and be done with it mr. cheap guy and it good for another 10 yrs a whole 30 bucks big deal
Bad starter solenoid. Bad brushes more likely (worn out)

it isn't logical to remove the starter, dissasemble it, and attempt to fix it. if you are going to do that much work....REPLACE IT. "isn't logicial" what are you nuts!! it takes two little(but long) bolts to take a starter apart and a whole 20 minuets to replace the brushes. why the hell would you pay 100-200 for a "referbished" starter; or god help you 250+ for a brand new one when the brushes cost 10-30$. just make sure it is the brushes and not the drive gear(look for pits in the copper lines) those things tend to get expensive, usually as much as a referbished unit. ~isn't logicial LOL i bet that guy works for the government~ The best place to buy starter/alternator rebuild kit(or individual pieces) are repair shops/electrical stores that deal only with starters and/or alternators **My starter for my gmc 2500 was only $30 at Auto zone....all shiny

when it wont cranck over
Typically, when the solenoid fails the starter is right behind. If you know how you could replace the solenoid, put in brushes and bushings and the starter MIGHT be ok if nothing bad has happened to the armature.

the reason for brushes is to makethe motor revolve. The more brushes probably make a more powerful starter motor
The starter is bad and the brushes need changed you can change them your self for dirt cheap or replace the whole starter for more money.
Pull starter apart. Clean commutater and the grooves in the commutater. Make sure the brushes are good and reassemble. Should work well.
