is there a trick to putting on the side cover and getting the brake disk to line up?? the mb is new to me, i had trouble getting the disk to line up between the pads, i fired it up for the first time yesterday, when i hit the brakes the disk was on the wrong side of the pad and melted into the side cover. i have been building and running 1/10 scale for 20yrs so im not a newbie by far. but this is a PITA!!! thanks in advance for any help.
