Brake change help

[fawcett]

Ok i have to change the brakes on my uncles 01 silverado 1500. the fronts are so gone and it is so unsafe. i worked for my uncle for over 10 yrs and he gave me this truck. its not my cup of tea (pos chevy) but the price is right (free+no insurance payments+commercial plates so i can get drunk and park wherever in boston). so the brakes are gone, i got all new brake shoes and rotors, jacked it up, took the tires off then i couldnt get the bolts holding the calipers off. they are stuck on. i made an extension for my rachet using a pipe and i tried beating it with a shortie sledge hammer with no luck. im thinking i need to torch the hell out of the bolts but im scared because the brake lines are right there. i tried using some spray stuff to brake the bolts lose but again i had no luck. what do i do, someone with experience please help me out!
thanks

try the heat as the bolts are probbaly locktited.. then cool everythign with some penetrating oil...

Think big socket (6-point) with a lot of leverages so you can apply a nice smooth force to break it loose....

Worst case cut the bolts and replace them if you can or replace what you need to...

try soaking bolts in PB blaster?

Yeah that is the ticket. Try PB blaster, and if that doesn't work, try Buster. That stuff is expensive but it's the best stuff I have ever seen. Our parts dept. charges 19/can but I am sure you can get it for 12-13. It takes the WD out of WD-40.

Secondly, as others have stated, you need a 2ft breaker bar attached to a 4ft pipe. Then with someone else keeping the socket on the nut evenly, you turn that bastard!!! Don't strip the head otherwise it's FUBAR'ed

FYI, you need to have the name of your company on your truck as well now. Just comercial plates wont get you by anymore in boston.

It takes the WD out of WD-40.

WD-40 still does a great job doing what it was invented for. . .Displacing Water (i.e. Water Displacer #40). Use it under your distributer cap or spray a little in your cylinder bores to keep water from rusting them.

WD-40's mild abilities as a penetrating oil are more of a fringe benifit than a key use.

Take a styrofoam cup and fill it with water. Then spray some wd-40 in it......nothing happens.

then take another cup and fill it with water, and spray some Buster in it. You will have a hole in the bottom of the cup instantly and the water will pour out.
