Does anybody know what correct torque is for the caliper mounting bolts. My manual says 38 to 48 ft. lbs. I torqued to 38 and stretched bolts. Tried new wrench and bolts and it happened again. Called Ford and they said they don't have torque spec. for these bolts. Tried brake shop and they said same thing. My truck is a 97 2-wd.
