Torque Values

I'll be mounting my new tires tomorrow under supervision of a TC170A member and A&P. Can anyone tell me the torque values for the wheel bolts and brake caliper bolts? I have Cleveland wheels and Cleveland double puck brakes.
Thanks, JP White

I believe Cleveland has their service manual on line for free.

Thanks for the info guys. Looking forward to my first tire change this morning. You must be an airplane nut to look forward to this!

The Cleveland Technician's Service Guide has the same information you are looking for except in a simpler, shorter format. Here is a link to it (I hope I've done this right):

Yes indeed, very bad. This may be the most common mistake that mechanics make (owner mechanics AND A&P mechanics). Not just brake calipers, but tightening/torquing in general. I've watched behind and inspected behind many very experienced mechanics. Over torque, by a very large margin, takes up the largest chunk of the pie chart in mechanic mistakes. Most folks, including myself sometimes, forget about the leverage the tool offers.
