What is the actual torque for the SS rear brake banjo bolt?

Hey all,


So my car had a stripped bleeder bolt on the passenger rear caliper. I decided to replace the caliper and during my install today I got 99.9% done and then decide to check the torque on the banjo bolt. As I did so the dang bolt stripped inside the caliper. I pulled the bolt out and saw shards of metal on the end (from the caliper side). I didn't think my initial tightening was anywhere near 30 ft pounds and after doing some research I'm seeing quite a few cases where others tried to do 30 and ended up either stripping the caliper or breaking the bolt.


Also, apparently Corvettes also suggest 30, but I saw quite a few people saying to use 15 or so ft pounds.


So, what the heck do I do? I already ordered my second replacement caliper and I really don't want to mess up another one! Official GM values from what I see do say 30, so I'm totally confused.



Thanks!

The Haynes manual also suggests 30 ft/lb. I've done brakes a bunch of times on other cars and never torqued the banjo bolts to spec, just used a small wrench and went with what felt to be tight enough 30 does seem like a lot to me but then again what do I know

Well, I initially got it to snug, and then was like 'I need to go by the manual', and in doing so stripped it. :(

Was this a Brembo Caliper?
