97 3500,rear brake wheel cylinder. The link rod comes out of the wheel cylinder and pushes on the brake shoe at an angle. The cylinder is a chevrolet and was instaled because it is larger. Is the angle ok? The chevrolet cylinder change came from a blog on TDR. More braking stops better when pulling a trailer, used to have a 30 ft toy hauler. Too sever braking for just the truck. I am 81 and going threw a devorce, so its just me and my dog and my truck. Life is a lot better now. I live in Pahrump NV now. Real friendly town. My new girl friend has been telling
