its a pretty simple job, I try and rock the caliper back and forth on the rotor to open up the pads so it comes off easier, pull the little clip off of the top and unscrew the holding pin, then squeeze the brakes with the old pads and clean with brake cleaner, then with the old pads I put a screwdriver in to open up the gap again and replace the pads, then bolt the caliper back up, I don't have the torque spec handy but I definitely use a torque wrench on the caliper bolts. its about a 5-10 minute per caliper job.
