I have 2000 Galant and the process is the same way with your 2001. Remove the tire. Using a power wrench remove the two srews that hold the caliper, this is what puts pressure on the front break pads. Make sure you dont remove the break fluid line or else there will be a mess. Then with long screwdriver put pressure on the caliper unit to push back the pressure ring inside of the caliper. This will help put the caliper back on over the new break pads. Next remove the pads. Make sure you save the heat shields and put them on the new pads. Installation is the reverse.
