I have an old home made jig that we used to run in 540's while putting "braso" on the bushes.
Took to long, the motor in a glass of water ,and tooth paste works best.
As most know tooth paste is like 2000 grit sandpaper, so it grinds away at the bushes, and brushes.
And as far as the bending of the "leaf" brush bending, it does work but it is illegal.
My way for a meet used to be ,run the (new) motor in a glass of water, with about a tea spoon of tooth paste.
About 10 minutes.
Dry off the motor, then spray it out with "BAZ IN A CAN" (now use orion or trinity motor spray) ,let it air dry.
Put a drop of bushing oil on each bushing ,then work the armature up and down ,and spinning.
Put it in the car ,but with a pinoin gear 2 teeth lower than you would normally run, I used to do this for the first 2 runs of the day, because this helps bed the brushes in better ,and also how often does TQ be set in the first 2 heats???
Give it a go, and good luck.
