If the brake lever is releasing far enough, it should almost touch the pin that holds brake shoes to backing plate. I'm assuming you got the cross bar from another 11 inch brake setup? That's what the truck has, no? Also, you have adjuster cable in between return springs instead of behind them both, although that's not related to brake lever isssue. Be certain the cables are releasing all the way, you may have to back adjuster off at cable, stuffs probably frozen(rust)
