OK folks, for those in or near their rigs, and resting up this Sunday, please (un-plug) and go out and pull your pin and tell me if you hear your brake magnets "click", or "clank and hummmm". We'll all get data on this question, and you'll have done an important safety test of your breakaway switch. Thanks--- Jim
Just what I would do.....
Get a wheel off the ground, spin and have someone pull the switch just to make sure.
Our Classic really don't 'hum' much but the brakes work fine.
