So I was forced to a brake job the other night, after installing new suspension on a mustang, to put it simply, tired and annoyed. Replaced rotors and pads on the front, pads on the rear. Put it all back together and trust the impact to keep the bolts on, bad idea. Drive home, pulling into my apartment i hear some clunking from the brakes. Check it out in the morning and the left rear caliper is almost completely off. One of the bolts fell off somewhere. So now I'll go reinstall all the bolts with threadlocker.

However, I need another caliper mounting bolt, and no where seems to stock them specifially. I'd try an LKQ, but finding an SS/rear disc cobalt there would be difficult. Does anyone know what bolt it is, or if it's the same as the front?

Thanks in advance.

 

should be the same as the front

if you need to fix the car quickly you can prolly get some non oem ones at a auto store

 

I don;t believe they are the same as the front.
Here's the right part number (plus my comments from another post)

Old and new caliper bolts with PN for future generations lol. I'm not sure why they made these bolts longer, there was really no need for it. It doesn't hurt anything either, as the bolt protrudes inside the "hat" of the rotor.

 

I have a parts car in the garage. If you still one I can pull it and send it.

 

You can grab a replacement from Lowe's - I've done it. Just take in one of the old ones.

Utilizing torque specs will typically prevent things like this from happening.

 

To update this thread, I ended up paying the $6 at my local dealer who had 1 left in their inventory. I ended up using blue threadlocker on every caliper mounting bolt, front and rear, and torquing again. We had torqued the bolts previously, but admittedly, we were a bit tired. Thanks for everyone's comments, and hopefully others can come here since I wasn't able to find anything before.
