I had to take a rotor off of my 05 Saab 9-5 yesterday and got into a confusing situation with the bracket bolts going back on. Torque spec is 103 ft. lbs plus 45 degrees. I took the bolt to 100 (limit) with my clicker torque wrench and then went over to my beam wrench. Torque climbed to about 120 and then leveled off. I was able to get about 20-25 degrees of the 45 (car was on jack stands). I ended up doing all this twice because I didn't like how the quarter turn was going.
I'm wonder if I'm okay with where I left things. I'm short of where the specs are, but I'm a little concerned about the flattening of the torque as I was attempting the quarter turn. Was the bolt stretching or a washer flattening? I haven't seen anywhere where it says that these bolts are single use, but am wondering.
