Not sure what the brand is. I know that he bought it from "Classic trucks,but didn't ask for advice,first. The unit is for 1/2-1-ton.And according to some expert opinions here,on the "Bolt",those units aren't sufficient in stopping a bigger truck. Another possibility,( I suggested),would be to try to adjust the "Stars". Maybe the wheel-cylinders aren't pushing the shoes against the drums. My answer was: "If you turn the "Stars" out too far,it will pop the caps off of the wheel cylinders". I give up. That's how I adjusted mine,and they both helped! I'll keep you posted! E-brake was known to be safe,before the excursion began. Thanks for the replies!
