You're more than welcome!
There was corrosion on the bracket bolts as well as being so tight. So I wanted to be able to get them off if I ever had to "in the field." I think I used a 3/4" drive stepped down to that 21MM socket to get them loose at first. Also, when I simply replaced the pads, the contact pattern on the rotors was really spotty. So I took them off to have them turned and I re-packed with new seals for reassembly. I don't worry too much about torque on things like those bolts. The goal's to German-Tork them: gutentite...
