What is the size, length, hardness of the rear caliper bolts ? Do VW shops carry them ?

Why guess? I'm sure Bruce Stone will have some plated and looking pretty. Give him a call...just a suggestion as he's local and good to deal with.

Good idea, thanks for the tip For some reason, I thought caliper bolts were not reusable ??

Why? They're not torque to yield bolts, which were probably not even commonly available when these cars were built. If the manual doesn't say "REPLACE", don't.

I just happened to measure mine last week for replacement.
12mm x 1.5, 30mm long.

Thanks Ho about hardness ?

They are grade 10.9. Do you need 4 or 8?

Also please don't electroplate 10.9 bolts due to the risk of hydrogen embrittlement.

For some reason the Bird includes new bolts in front caliper rebuild kits.
My old ones were perfectly good yet, so have some more stuff in my metric bolt junk jar

He needs longer ones. Jim, we have them. I'll send you 4.

Originals (Kamax) are 8.8 BTW. Aftermarket replacements are 10.9

Here's an original next to the ones we're sending Jim.

Wow! You stamped his initials (JH) on the bolt! You are so awesome!

Says 8.8 and made in Taiwan.....

We had them custom cast just for Jim. He's yet to see the bill but, we have all his card info.

Eric, what is the correct length. Instead of that crap from Taiwan would you be interested in a Kamax bolt grade 10.9 and a better finish?

JH =Jinn Her Enterprise located in Taiwan ROC

7 N0101274 hexagon-head bolt m 12 x 1,5 x 30

Assuming JH has stock rear calipers?

I've never even THOUGHT about replacing caliper bolts. I wonder if I should have. Hmmm....

Great info though. Thanks!

Clarification: The rear calipers had spacers added to accomodate vented rotors

Those are McMaster replacements in the 35mm size. He has to space his calipers 4.5-5mm off the mounting ears.
