DON'T LAUGH! What is a good nut loosener?
 

I am trying to replace my front rotors and when I tried last weekend, the two nut's or bolts that hold the caliper on, would not budge! I beat the hell out of them and they would not move.

Does anyone know of a good way to loosen them so I can get them off? Is there a spray I can put on them that will help and WILL NOT harm any of the other components around the caliper such as the rubber boot or brake line?

Thanks in advance for your help with this. I can't believe that two little bolts are keeping me from doing this simple project! :smash:

Liquid wrench.

That works well? Can I get it at the AutoZone? I will try that this weekend and see what happens. Thanks :)

Autozone, advanced auto, Wal-Mart...anywhere.

I'll check it out this weekend. Thanks again.

Well I try doing the break job on my car and I broke the two pins (bolts that you are talking about (if it is the same as on my maxima) 2 new pins for you to buy at CAP cost $19 dollars)

Oh cool. Well at last there is something that I can break while trying to work on my car and it won't cost me an arm and a leg! LOL

Thanks for the heads up Guinader, I appreciate it.

hopefully I will be able to loosen the damn things and just have one project that goes smoothly. lol

Hey I can tell you a good nut loosener is a hot girl with hands as soft as cotton. LOL
Just kidding, really you can use liquid wrench or wd-40.

gqmac2: LOL I knew it was only a matter of time. :)

I tried WD40, but it didn't work for me. :( I think I will try the liquid wrench this weekend and see how that goes. It is alright to use near the brakes and all? I want to make sure whatever I use does not harm anything else.

Thanks again :)

A bigger wrench maybe? That always seems to work for me :doublethu

no, a bigger wrench did not work. believe me I tried it. like I said, i nearly busted my freaking back trying to get these nuts off. STOP LAUGHING!!!! LOL

What TOOLS are you using to try to break them loose?

I was using my Craftsman mecanic tools. The big socket wrench. I even put the wrench on it and beat the hell out of the handle with a hammer. nothing! :(

You have to "snap" the bolt free with a jerking motion, not with banging or constant pressure. Really, you need to "snap" it free AND keep the bolt moving with constant pressure.

Are you using a breaker bar, or a socket wrehch? How long is the handle on your wrench?

And is it a 12 pt. or 6 pt. socket?

When you say snap it free, does that mean that I will need two new bolts because I will be breaking the old ones???

I believe I am using a 6 point socket and the handle is about 12 to 15 inches long maybe???

The bolts holding the caliper housing/frame (not the actual cliper) look just like the bolts that you unscrew to get the caliper off to replace the brake pads. I would have thought they would work just like the other ones.

This was supposed to be a couple hour project at the most, and these two stupid screws are making it not fun and quick at all. :( LOL

I figured I would have to take it to a shop where they can use their power air gunes to loosen them for me.

Thanks for your help, I am hoping to change out the rotors this weekend.

No, i mean that over time the bolt rusted, chemically bonding it (weakly) to what it is touching. You need to physically break this bond with force. You should NOT break the bolt.

You may need a longer handle. Try a pipe over the handle of the wrench to give you more torque.

Ok, I get it. I will try this and let you know what happens. It is still safe to use liquid wrench as well correct?

Yes, it is completely safe.

cool, I will let you know what happens. Wish me luck! :)

PB Blaster, available at Wally Mart, works way better than anything else.

Thanks ob1stogie. That is funny that you mentioned that because I just got back from the auto parts store and that is what I picked up. LOL

I will let you know if it works.
Thanks.

Well guys, i did it. I changed out my front break pads and my front rotors tonight and it went pretty smooth. I used all of your advice and bought some BP spray stuff that works like liquid wrench and it loosened the bolts (on the left side after an hour or so of banging and spraying) and I was able to finish the job. The right side took about 5 minutes from beginning to end! :)

Now I know this is not a big deal to most of you, but for me it is because this is the first time I have done mechanic work on the car by myself and so it is sort of a victory for me. I could not have done it without all of your help, so I thank you.

Have a great day everyone. :)

use your teeth ....duh

j/k damn calm down
