I just replaced the brakes (front discs/pads, rear wheel cylinders/shoes, and
upgraded to stainless steel lines all around), and now, no matter what I do
with the parking brake adjuster under the rear passenger area, the parking
brake doesn't fully imobilize the bus. (i.e. w/the bus stopped and the
parking brake on, if I put it in reverse or drive it will still move. What
can I do about this?
