There are two bolts (17mm head) on each caliper, one on top, one on the bottom, both on the inside of the wheel. The one on the bottom can be removed with a ratchet, the bolt on top will need a box end 12 point wrench due to the limited space given to work with. Remove these and the caliper will lift off the rotor. Using a flat blade screw driver pry the old brake pads from the bracket without bending the bracket. These will be reused with the new brake pads. With a "C-clamp", or similar device, slowly compress the brake piston. (You will notice brake fluid leaking from the reservoir. Have a drip pan ready if you don't want brake fluid on the floor or ground.) CAUTION: If the piston is compressed too quickly the pressure could damage the cylinoid. Make sure the brackets are secure in the caliper and relatively clean. Set the new pads in the brackets just as the old ones were making sure outside pad and inside pad are on the correct sides of the caliper. Resecure caliper with the bolts that were removed. After completing both sides, before driving the vehicle, pump the brake petal to recharge the brake line and set the new pads against the rotars. This should take only 2-3 pumps before noticing a change in pressure. Good luck.
