My brakes grab on my Colorado Canyon pickup
GM reports a problem with the rear brake shoes glazing over and grabbing or dragging against the brake drum. The self adjusters are to blame. GM has come out with a replacement star wheel adjuster for the left side only (part #19133371). On the right side, GM wants you to use a high speed grinder (like a Dremel) with a cut off wheel and cut off every other tooth on the star wheel. Then reassemble and adjust the shoes.
How long has GM been making cars with drum brakes? And they still can’t get it right?
