when changing the brakes on an 04 silverado, I need a torx bit I think to remove the caliper, but no size fits the head of the bolt. I've used every size possible. Is there a vehicle specific tool used for that brake? If so, where? and if not, what could I do?

It's not a Torx screw, what you need is a Hex key, or more commonly referred to as an Allen Wrench. The main difference between the two is that the Hex key is hexagonal, as opposed to the Torx which is hexalobular. Basically, the Torx is a Star shaped bit, and the Allen has 6 flat edges. I'm not sure of the size of the Allen Wrench, but I believe the size to be 1/2" or 3/4". If you have Allen wrenches at your need, try all the sizes till one fits. It's not that hard.
