New brakes all the way around for my 05 Escalade, I decided to upgrade to the NNBS bigger brakes since I'm getting into the system anyway, I also purchased new 05 brakes for the rear of my truck as they seem to drag a bit by looking at the old rotor.
Anyway, I grabbed the torque specs from the shop manual and proceeded to strip out the banjo bolt caliper threads on one of the brand new rear calipers.
Shop manual states 30lb/ft for the hose to caliper bolt, didn't even get close before the threads let go.
I didn't find any mention of torque specification on the forum but elsewhere I see a lot of references to stripping out the banjo bolt due to bad references from the shop manual. The CorvetteForum seems to have had several threads where a brake caliper replacement results in the same outcome with an unusually high torque spec.
So a warning to all, if you replace the calipers or brake hoses on your trucks, make sure NOT to use the factory shop manual torque spec. I can't find any official specs for our specific trucks on the web but what I find seems to be about half of what my shop manual had listed for aluminum calipers.
It's off to Advance Auto I go for some new rear calipers, which I see listed are aluminum as well, another $100 and an hour or so out of my day to make a parts run.
Correction to original post. Stock calipers were aluminum as well as the replacements I picked up. Just a flat out WRONG torque spec in the factory shop manuals.
