Hey guys, was doing my front brakes today and noticed what im assuming is a coil thread insert that was coming out. Im just wondering if these are OEM at all and if I can possibly just buy these at the dealership or local parts store or if I can just get a bolt that fits right into the oem thread. I recently bought the car used and as far as I know all the other mounting bolts have the same coil thread and have screwed in with no issues. Thanks!

 

Welcome to the forum!

So first thing, the threads aren't supposed to come out.
Your last pic of the thread sitting on the bucket looks like a heli-coil.
Meaning that someone before messed up the thread in that hole, and used a heli-coil to repair it.
Clearly they didn't do the best job and the heli-coil has now come out.

Options:

1. Get another caliper (new or used)
2. Get another heli-coil and fix it properly (or get someone to fix it for you)
3. Get a Time-sert thread repair kit (instead of the heli-coil)...Time-serts are much better than heli-coils, but also cost more

When they inserted the heli-coil they would have had to make the original hole bigger in order to fit the heli-coil, so that you could use an OEM bolt again.
If you can find a local machine shop, then can fix that for you easily.

 

Thanks for the reply. Some mechanic friends did say that the thread looks fine still and I can try inserting another helicoil in. Since the bolt is an M12 x 1.25, im assuming the helicoil would be the same yes?

 

I haven't measured the bolt to confirm the size, but M12x1.25 seems correct.
If so, then the heli-coil would be the same to bring the hole back to those dimensions for the OEM bolt.
I would suggest there must have been a reason the first heli-coil came out...maybe poor installation or there is something wrong with the hole still preventing it from staying in place.
