   Brake caliper torque

   This is a question mostly of your experience as the older I get the less I   
   tend to use torque wrenches (I've had more problems with them than without).   
      
   Kids are in college so they came home on spring break and I did their oil   
   and filters & wheel rotation and brakes which on these FWD overseas economy   
   cars is so simple as to be considered ridiculously easy.   
      
   It's so easy that I'm beginning to get just a little bit lazy over the years   
   (on my own cars also) in that I torque by hand most of the time nowadays   
   (except when dealing with softer metals than steel bolts on steel threads).   
      
   For an example of how easy things are nowadays, all four front brake pads on   
   an old Toyota Camry are exactly the same as are all four of the shiny steel   
   clips and as are the two bent metal wear sensors so you can't even mix   
   anything up.   
      
   I replaced the steel rotors after removing the two 14mm steel bracket bolts   
   and two 17mm steel caliper bolts. I didn't have the torque figures so I   
   tightened the caliper bolts up as tightly as I could using normal sized   
   sockets (half-inch socket wrench with about six or seven inches long   
   handle).   
      
   I also tightened the five lug nuts using a standard sized bent angle lug   
   wrench (the kind shaped like an elbow with about a foot or so of handle).   
      
   My question is mostly about the calipers as I did have the torque figures of   
   about 85 to 90 foot pounds for the lug nuts but I didn't have the torque   
   figures for the 17mm caliper bolts and the 14mm caliper bracket bolts.   
      
   Given a normal strength male and a normal sized socket wrench handle   
   is it even possible to overtorque steel on steel nuts and bolts of those   
   sizes?
