don't snap the small bolts that hold the caliper to the bracket when re-installing, buy and use a torque wrench since you don't do this every day. and use the proper lube in the proper places and keep it away from the wrong places. clean the rust and crap from the hub where the rotor seats with a wire brush, you can use a LITTLE anti seize on the hub where the rotor seats, but anti seize gets thin and runs under heat, such as w/ brakes, and it will cause problems if used too much. clean and lube the caliper guide pins w/ brake lube designed for calipers. syl glyde is one name for it, but there are others, it is designed to hold up to the heat. do not use anything else such as grease, or anti seize there.
use a large c clamp or huge channel locks to push the caliper piston back in, or there is a tool designed for this.
and if the idiots at jiffy lube have been topping off your brake fluid, it will spill out when you do this, so make sure your brake fluid isn't full. that really angers me, you should never add brake fluid unless the system was opened, bottom line, if its low the brakes are worn, or there's a leak.
ok......rant over. good luck.
