I’m curious, how long is your 3/8 ratchet handle? Pretty hard to get over 80 ft lbs using a dinky short ratchet.
That’s why 1/2 is used, for breakaway and the leverage needed to torque to the correct spec. Caliper bracket bolts are pretty important to be tightened correctly.
Yea man I usually try to use something with at least 12in handle in order to get enough torque.
Usually caliper bracket bolts are anywhere from 65 to 115 ft lbs torque in most cases.
You do not want those to fall out.
