tires and brakes on my four winds chevy 3500 chassis

I watched that video on youtube and he didn't have that much trouble getting the caliper bracket off...locktight does make it tough. Generally that stuff will break loose with a sharp rap on a breaker bar. Now if the wrong type was put on it can be very difficult....heat works...so does loosenut spray. The inner nuts on the hub is what I am concerned with since you have to cross jam the wheel with a bar across the lug nuts. Just takes time and muscle.
Thanks
