<<<This is about the time where you would be moving on to install new brake rotors if you were taking on that project as well. Remove the carrier and remove the hex bolt holding the rotors on and take a BIG hammer and whack the old rotors off. Reassemble, torque carrier bolts to 68 ft-lbs and the hex bolt in front to 12 ft-lbs.>>>>
Next, you need to remove the old brake pads and install new ones. Here's the snag: the old pads will be thinner than your new ones. So, the piston will be extended to far for you to install your new ones outright. Solution: big clamp!
Next, lube up your new pads were the pads contact metal, and push them in. If you are on a wheel that requires a brake wear sensor, don't forget it.
