brake caliper bolts stripped

[sunroom2004]

I stripped out a steering knuckle bolt hole by overtightening the top brake caliper bolt. I only drove a few miles on test drive and then parked it yesterday. Today I found the top bolt missing and the bottom bolt had damaged the threads where it screws into the steering knuckle.

I wanted to check what options I have besides just buying a new steering knuckle? The main options I can think of are drill out the knuckles and install heli-coils or just try re-tapping the hole threads?

Re-tapping may not work well because the holes seem larger than before. I can put the bolts nearly 1/2 way deep into the hole until the threads start.

thanks!

Thanks. Yesterday I stripped out the driver side and then today I stripped out one on the passenger side! :banghead:
I'm going to try the helicoils tomorrow and if I strip out those, then I'll probably swing by. :)

Should I use red lock tight between the outer helicoil and knuckle and then blue lock tight between the bolt and helicoils?

Some people shouldn't work on their own vehicles hahaha


... use red high strength on the helicoil to knuckle, no locktite on the bolt

I'd recommend you go with green lock-tite for helicoil to knuckle, and a light oil to the new caliper bolt threads.. and if you aren't a good judge of torque.... um, get a torque wrench.

this happened to my jeep when i got it first thing i noticed that was wrong i ran around with the helicoil till i got another knuckle and replaced it it should hold

LOL...I'm starting to think any $ I save isn't worth the hassle! :laugh2:
I almost had it towed to DF yesterday!

I thought you were joking about green lock tight, but I looked it up. Their website says it's more for locking threads that are already assembled. They call this type "wicking" since it can penetrate the small clearance between threads.

My torque wrench only goes down to 20ft-lbs, so I may pickup one with lower range today.

FYI, the XJ/TJ caliper bolts should only be torqued to 11 ft lbs.

nothing wrong with helicoil, and they are cheap.

Personally, I wouldn't use them on brake parts. I'm sure they are fine, but used kunckles aren't exactly expensive.

Mr Blaine sells helicoil kits just for this occasion, stock are easy to strip and for the future the torque is supposed to be around 10 ft/lbs

i've used them in applications needing 5 foot pounds all the way to 90 on head bolts. The way they work in cast materials they are actually stronger than just cutting threads in the material.
but either way since its just a 30 knuckle should be easy to come by.
