So, I've had a squeaking going on and brought it in today to get checked out. I have a seized rear caliper and I'm told that I need to replace the rear rotors, calipers, and brake pads. I drive a steep 10% grade pass every day, and would like to upgrade the rotors to something that will dissipate the heat a little better. How hard is it to replace these parts, and what recommendations to you have for a rotor/caliper upgrade? I've been calling around and have been getting prices from $1000-$650 for the parts/labor and if it's not too hard would like to replace them myself. Are any special tools needed?
