Caliper Bolt Torque Setting?
RAVE says the front caliper bolts are to be torqued to 129 pounds. I was torquing it down to that setting and the head snapped off. I had a real nice afternoon and evening trying to extract the screw before realizing I could get a replacement guide pin at AutoZone for a few bucks. Wasted day aside, is that really how tight I'm supposed to torque the caliper bolt down to?? That seems excessive.
Caliper Guide Pins typically range from 25-35 ft/lbs
Caliper "Carrier" Bracket Bolts typically range from 35 - 125 ft/lbs
I believe you may have referenced the wrong bolt spec in Rave? But kudos to you for trying to identify the proper torque spec.

Oh gosh. Yup, I see where I went wrong. A couple lines down is "brake caliper guide pin bolt" at 22 lbs. Versus actual caliper bolt at 129 lbs. Phewie. Thanks for the tips guys.
Remember 129ft/lb is literally like standing on your ratchet wrench if you weigh 129lb and it's 1ft long.
So you can kinda idiot check the value by saying "would I stand on my ratchet, given my weight, and the bolt is 8mm."
I think the caliper bolt is 8mm or 3/8".

129lbs/ft is way excessive for either guide pin bolts or caliper carrier bolts.
I rarely use a porque wrench for most things apart from engine internals, head bolts and alloy wheel lug nuts.
I'm with cappedup on this one, think 129lbs weighing down on a 12 inch long wrench. These original bolts also have threadloc on them.
