dont u just love yanking e brakes in the rain! feels crazy having a tight back end! it rained like crazy here i had a little fun takin turns with the e brake handle feels great!!!! i yanked an ebrake one time and i only did a 180 but the car kept slidding backwards and when it stopped it shut off what is that all about?

 

this really has nothing to do with your RSB~~
it's probably because you have an auto and the ECU sensed that your gear is in D, but you're going backwards...maybe?
