Do not bet your life on a ruined thread.

Replace the caliper & sleep well.


edit to add.... my misunderstanding. If the hole that stipped is in the caliper braket? Then I agree with Gary Jeep Mud, auto parts stores have a simple fix for this common problem.

I don' t know anything about helicoils, but when this happened to me I went to NAPA autoparts and bought oversized caliper bolts, they worked great. they come with locktite in the package. just tell them your make, model, and year, they stock thousands, thats what she told me. good luck.

Here is your magic potion.

I just did this about a month ago myself and it is a great kit with all parts needed and good directions.

Any good auto parts store (i.e. *NOT* Auto Drone) will have Helicoil stuff. The resulting repair is usually as strong as the original. Be prepared for sticker shock. I buy my Helicoil stuff at Winchester Auto Supply in Campbell, CA, but most NAPA ought to have it too. Get the "kit" with the drill bit and inserter.

Helicoils are typically better in blind holes that have a bottom.

You are better served with a solid insert. I like the Timesert brand due to the flange, but they are so expensive and hard to buy in small quantities, about the only way to get them is to know someone at an auto shop that uses them.

If you do find some, the thread size is 8mm x 1.25 pitch. Just make sure you borrow the cutting tool to cut the counterbore for the flange.

A reasonable alternative is the EZ-Lok brand with the American external threads. Be aware that the dry patch loctite 271 on them is fairly useless and should be removed and liquid Red 271 Loctite used instead.

I did a lot of testing on the EZ-Loks after reading about some folks having issues and figured out a decent solution with the liquid. Also note that I tested the gel stick Red Loctite and found it didn't hold very well either.

I had a similar problem on my better half's Durango this weekend. I was able to get a tap from Napa and clean up the threads from the back side. The guy at Napa said if that didn't work they had a bolt with oversized self tapping threads made just for this issue. Lucky for me the tap worked. Good Luck!!

I went to my local NAPA they didnt have oversized caliper bolts for a jeep, only GM products.
Does anyone have a NAPA part # for oversized caliper bolts for a Wrangler?

I've been pondering this my ownself. I'm trying to figure out how you get oversize threads through a sleeve that is the correct internal diameter without drilling out the sleeve, in which case I'd be a bit concerned about it's final strength and ability to work correctly.

Having played with a few hundred jeep calipers, I'm a tad confused.
