Stripped front caliper hole

drano38 said:
I've got a new caliper on order from Tousely/Auto Nation.
$248, no core charge (that's odd).
Will be on my door step Tuesday. Once I'm up and running, I'll try to fix the damaged one.
Showed not in stock/backorder, but said he can get it somewhere else today (guessing another dealer).

Got new bolts today--John Deer 12mm 1.75 pitch 35mm long 10.9 hardness to get rid of the locktite. They have a bigger hex head for the wrench, but that won't matter--I'll swap out all 4. Part # 19M7790 if anyone wants to buy them at your local dealer.
Thanks for the update. That's a pretty reasonable price.

DO NOT use a helicoil, here's your solution....

you may need to counter sink the head but that's not a big deal and I see the new kits come with the counter sink. check out the sight, they have videos, you should be able to knock this out in 15 minutes.

Got the caliper today.
$248.18
$9 one-day shipping
$257.18 to my door.

Does not include copper washers so I'll pick up 2 of those Wed.
Now I can use the bad one for practicing removing/replacing the boots, and then install a Timesert. If all goes well, I'll Timesert the other side too this winter.

Now back to my oil cooler install--brackets made and painted, so now hoses and putting together.

I have an old caliper I was going to refurbish using timesert, but cannot find the 20mm long inserts in M12 x 1.75 anywhere. Any one know a good source?

Ordered two new fronts from Tousley today, but they went up a little bit. $534 for the pair plus a $50 core charge for just the driver side which we both found a little strange. I'm going to try Steve's approach of no Loctite and anti-seize to see if they get me through this season. I didn't want to spend $3k-$4k for a race set to use until the GT350 hits the market.

With updated brackets you'd be able to use the calipers on another car including the GT350.

What does anyone have against the Helicoil system?They are far better than any kind of threadsert.
They are aircraft worthy repairs.Edelbrock uses them in new cylinder heads.
If I strip a caliper mount bolt I will use a Helicoil repair.No need for any thread locker either,a
Helicoil can't back out.

I've seen them unthread with the bolt..come right out. Threadcerts are so much better.

If you have the metal around the hole to support on insert, then use an insert.

I have used inserts with locking pins in the insert. Press them flat once the insert is installed and the insert cannot be removed

Coils do come with their own problems.

Nothing wrong with Helicoil or Kato brand wire inserts and yes, there are even Mil-Spec numbers for these. Ultimately the solid wall Keen (Keyed) inserts are the best. The only issue of course is the cost as typically solid wall inserts are at least 10X the price.

Here's a good quick read on these types on inserts for thread repair.
