Running out of idea's, I have a 14" breaker bar that I have stood on and the the bolt still would not budge. Guessing the last time the brakes were done, they used an impact wrench with loctite. The rears were a breeze, but these fronts are kicking my butt, I am going to try some kind of anti-seize spray, but short of a sledgehammer, I do not know what else to do.

 

Let the bolts soak overnight in whatever anti-seize solvent you're using, and use a much longer breaker bar for significantly more leverage. A metal pipe section maybe three or four feet long would be ideal....

Good luck and keep us posted....

 

Have you got a heat gun, like a heavy duty hair dryer? use it on the bolt heads to break down the loctite, you also need a bar about twice the length to get it moved. It will come, they're just tight bolts!

 

I had a lot of trouble with this one.



And solved it with this bit of pipe.

 

A 50-50 mix of ATF and acetone seems the best penetrant.

 

Righty tighty, lefty loosie ? That's no joke. Sometimes laying on my back upside down I get more confused than normal.

 

I don't think we want any more details !!!

 

Try heating the area around the bolt, doesn't need too much, then tap the head of the bolt whilst someone else tries to loosen it.

In the marine environment this is the method we use and it works every time.

 

I used a long handle wrench and a 2 pound maul to free them up.

 

I used an impact wrench to free them up , came loose easy this way.

 

my rattle gun takes them off ok

 

If the bolt has lock-tight on it use heat if it is rusted I found using PB Blaster works for me. My best results are when I tighten then loosen with a little tap on the bolt. I hope that helps.

 

Finesse over Force. A five foot breaker bar is a recipe for one sheared off brake bracket bolt. Heat, vibration, PB Blaster, impact wrench, back and forth tightening/loosening are your friends. Just using the biggest bar you can find is going to result in another post about how do you remove the broken section of the bolt.

 

If you don't have access to an impact gun, use a sledgehammer. Smash the head of the bolt with authority as if you were attempting to drive in a nail with a single stroke. Use the heaviest headed hammer that can be swung in the space available. Strike with the hammer, attempt to loosen. Repeat until it breaks free; which given persistance, it most certainly will.

If you think that loctite was used, heat will soften it. If you don't have an impact wrench, put a closed end wrench on the bolt, hold it there with one hand and hit the end of the wrench with a hammer in the loosening direction. Poor man's impact wrench.
