HELP!! Can't remove front caliper bolt..

Hello, I'm new to the forum and am in desperate need of help. I am in the process of changing my pads and rotors. I have tried using a breaker bar, pb, impact, freeze off and heat. Nothing seems to work, when I used the breaker bar I felt it move but only in a way that felt like the bolt might snap.. Any thoughts? I need to have my truck back together by Monday and don't want to have to replace the bracket if I can avoid it..

Thanks in advance,
Looking forward to hearing your ideas..

 

What year, inside or outside and/or what bolt? There are some you do not touch. Pic's are helpful.

 

KdF, thank you for responding so quickly. Now that you mention it some information would be helpful. I have an 03 Tacoma with the 3.4 engine and 4x4 manual transmission. I already did the passanger side so I believe I am removing the correct bolts but here are some pics to show the problem bolt which I am pointing at with a screwdriver..

Thanks again for your input

 

How long have you been at it? Keep hitting it with pb. Don't force it. That's a one way ticket to snapsville.

 

Impact

 

I agree. Pb impact. Pb impact. That's how I eventually got the stuck castle nut on my tie rods. Impact gives a good shock without the sustained torque of the breaker. You can also try tightening then loosening with the impact. Go back and forth

 

Breaker bar to break it loose then impact gun andbit will come out.

 

Are you heating the bolt itself? I try to heat the material the bolt is threaded into but not the bolt itself in hopes it will expand a little.

 

Edit wasnt thinking lol

 

Maybe that's why it rarely works for me

 

Don't listen to me I wasnt thinking...hahah

anyways id let it soak overnight if you can then go at it again (pb blaster or atf/acetone mix)
