    24 in breaker bar? Never had one yet that that wont get off. Breaker bar and pipe if needed, breaking the bolt no big deal get a semi loaded caliper it will come with a new bracket if needed. Sometimes hitting the bolt with a air hammer will help loosen it Just be carefull not to mash it so a socket will no longer fit.

    Just keep it away from the brake line. Don't want to melt it obviously. I have heated things many times and it 1. always works and 2. has not caused any problems. HOWEVER, I am not a mechanic or an expert on how the heat will affect the bolt so do not take my advice as 100% fact.

    You can heat it. A propane torch wont get it all that hot. Just be careful heating it up after spraying on PB. Will flame up for a sec but shouldnt be big. Id put a closed end wrench on it and tap it with a hammer. Get a better impact on it maybe borrow one.

    I always take the jack handle and unscrew the two pieces and slide the longer one over the wrench or ratchet and use that as a breaker bar. Works sometimes. If that dont work head to the gym and find some young hotshot and tell him you bet he isnt strong enough to get these bolts off. Thats works for both you. He gets another hard on about his strength and you get your bolts free :D

    Don't heat the bolt...heat up where the threads of the bolt go in on the break caliper bracket, this will heat up the lock-tite and it should walk right out and you can use a small propane torch for this.

    DJ is correct, if possible heat the caliper mounting bracket where the bolt threads in evenly. Then, if its a later model truck it should be an E55 torx, take the socket and place it on the bolt as if you would try to loosen it and give it a couple good whacks with a large hammer. The socket will protect the head of the bolt. Then grab your breaker bar and a large cheater bar to put over it for leverage. The trick is a lot of slow even pressure, quick jabs or jerks are how bolts get broken. Done literally hundreds and hundreds of these, they are all freakin hard as heck to break loose, a lot of times even air guns wont budge em!

    thanks for the advice i got it off before reading the rest of these after my post. i heated the bottom and not the top casue of the brake line and got it out with the breaker bar.
