I have a friend with a 1996 GMC Yukon with 120k and he is trying to adjust the rear brakes. GM cars and trucks have traditionally had a port stamped in the back of the brake housing that you can knock out and put your adjustment tool thru to tighten or loosen the rear brake shoes. This truck has two ports which are covered with black rubber inserts. However, they don't line up with the adjustment wheel. They are apparently to inspect the brake shoes without removing the drum. How do you access the adj. wheel or gear?
The wheek adjuster is just about under the brake cylinder on the top side.. There isn't any port to open up here.
