Last I noticed, timecerts and/or helicoil kits were considerably south of a C-note!
Where was this kit sourced?
From a machining standpoint, I would have fabricated a mock up drill jig and and a right angle drill to try to keep things perpendicular to the caliper mount face. Otherwise, remove the part and do it correctly on a mill.
Having an existing hole that is perpendicular to the mount face, makes the job so much easier!
p.s. Nice install...cleanly done!

you must have a great source to get considerably south of $100.
the time-sert kit needed in this application is #121505.
I was only able to find the M12x1.5 20mm length kit by calling time-sert and ordering direct for $103 plus shipping.
it'd be useful to know a source considerably south of that price, or even a source that carried the #121505 kit.

Not "considerably" under $100, but where I source my Timesert stuff: https://www.belmetric.com/ts1215-m12...th=217_218_240

I called a handful of those type of places timesert lists as a distributor, quite a few more at the same price point on amazon and ebay. none carry the correct part number or insert length and 10 bucks isn't enough for me to use the incorrect part.

Timesert is not the same as a Helicoil.
Helicoil may be an acceptable repair, but Timesert is preferred if you have the option... I read that in a Holiday Inn once so it must be true...

Really? I'd be thrilled to hear the reasoning behind such a bold statement. ![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)
You do realize that time-sert and helicoil are synonymous with each other, right?
So in this application, I'd love to hear your rationale... This should prove interesting!

timesert is a brand name
http://www.timesert.com/
and provides an exact fit for this application.
your example while cheaper doesn't provide the needed drill and the insert is short by 2mm.
you should instead claim to spend considerably south of a c-note by using a different product.
or provide your example of time-sert kit #1215J or 121505 available to purchase for considerably south of a c-note.

Right in the wheelhouse of 2.7L stud pulling was when he made public what they were doing at Garretson re: proper repairs. I happened to stumble right into 911 ownership, and my own plight with 2.0L issues at the same time to get it straight from the horse's mouth. Invaluable.

There are those who will claim theirs is the better product, but they really are the same in application.
If I had a deep hole I needed to repair, I'd use a timesert; if shallow, a helicoil woulld suffice.
The caliper is clearly a shallow depth hole, and helicoil kits do indeed exist.![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
Will either fix the issue of pulled threads? Yes
My intent was to provide a less expensive, yet viable alternative; not find and fix the exact hole size. ![Roll Eyes (Sarcastic)](https://rennlist.com/forums/images/smilies/rolleyes.gif)
You can always go longer and remove any excess thds. Oh yeah! What a concept...
Proof positive you can lead a horse to water...

that could be the problem, you think timesert is a generic solution to damaged threads so you make a bold statement it costs considerably south of a c-note.

So.. An elevator is synonymous with an escalator because they both get you up a floor?
I won't debate the applicability of either solution with you. But to say they are the same and work the same is a disservice to folks reading this forum looking for a solution.

I stick by what I said...both are viable fixes for the same problem of pulled threads, and my statement to this effect, is not by a longshot; a disservice. Thats simply a statement out of ignorance.
I worked as a journeyman machinist for 15 years at a Naval Weapons Air Station. Where are you fellas pulling your knowledge from?
We repaired stripped or buggered main feed pump case bolt holes with helicoils all the time under engineering direction. 1200 lb super-heated steam @ 800 degrees is a fair amount more stress than a car caliper mount bolt; although both are safety critical in their own right.
Of course they are not exactly the same, nor did I say so....I said they are synonomous with each other; and I said for this application.
I would not hesitate to repair a caliper mount hole with the less expensive helicoil, as this repair will have stronger threads than the initial parent material before the fix. Beyond this point is just overkill.
While in the pictured example, the timesert itself is clearly more robust as a "standalone" component, both inserts are screwed into the SAME parent material, where the extra material in the timesert is pointless. All you have really accomplished is removed more parent material than necessary to repair the threaded hole.
Do I believe a timesert is worth 40% additional cost? In this instance and for this application, nope!
However, if the OP wants to spend over a $100 to fix his issue, that is certainly his perrogative. But again, both are acceptable fixes for the same problem; one simply costs less.
