Carrier steering woes

[Snowtractor]

used to be a common pratice to grind the heal and toe of most shoes before putting them in . Most shops had a machine and some have newer vesions with covers and vacuum for asbestoes dust etc. you can use a hand rasp but the dust is a hazard. Now , with autos , we go out and make 6-10 sometimes more , heavy applications of the brakes to help set them. Perhaps multiple heavy applications in a straight line would help, though you are risking track stretch.
