Brake calipers & brackets bolt sizes
Got a new set of rotors powder coated calipers and brackets in the mail. Just wondering what size sockets and wrenches I need to do the job. Want to make sure I have all the right sizes before I start. Thank you

Caliper bolts are 15 mm and I'm pretty sure the bracket bolts are 21 mm....torque the caliper bolts to 23 ft. lbs. and 125 ft. lbs. for the bracket bolts

I just finished my rotor/pad install and the caliper bolts do take a 15mm but I used a 13/16 socket on the bracket bolts--also I recommend that you use 6 point impact sockets, at least on the bracket bolts as they can be a bear to loosen if its the first time. And you'll need a 16 mm open end wrench for the inside caliper nut on the front and a 18 mm for the rear.
Good luck--this was the first time I ever did anything to disc brakes and it took me about 8 hours overall, including 2 trips to Advance Auto for blue locktite(there's about enough for 4 bolts per small tube).
You might want to watch this video on how to loosen the rear bracket bolts. This worked great for me and I even tightened them using the same method(it's hard to get your torque wrench on the bolts on the rear).
