over time the carbon dust from the brush's gets in between the brush and carrier which stops the brush/s sliding freely, so a tap/bash to the starter body causes the brush's to move back onto the commutator,

I have only ever seen solid copper - I dont think carbon will last too long at 100-200 Amps!

no he isn't Vanny
the solenoid only supplies the brush's with current once it has fully engaged,
in my experience if bashing the starter gets it to work, the fault is caused by sticking brush's what ever they are made from,
usually if the fault is solenoid based the starter will either not do anything
or click or even try to throw the gear in but miss mesh,
