Change the Front Disc Pads on a 2005 Mitsubishi Galant

The front disc brake pads on the 2005 Mitsubishi Gallant rest inside the brake caliper. As you press on the brake pedal, a piston inside the brake caliper presses on the back of a brake pad inside the caliper. As a result, the pads create pressure on the brake rotor and stop the vehicle. The pads wear out much faster than the brake rotor and when they do wear out, you will hear a chirping sound every time you step on the brake. This means it is time to change the brake pads.Procedure:
1. Open the engine hood and remove the front cap from the master cylinder. The master cylinder is next to the firewall on the driver's side of the engine bay.
2. Loosen but do not remove the lug nuts on the driver's side wheel using the tire iron supplied with the Gallant.
3. Place a jack under the frame, directly behind the driver's side tire, and raise the vehicle high enough to place a jack stand under the frame beside the jack. Lower the Gallant onto the jack stand.
4. Remove the lug nuts using the tire iron and pull the wheel off the wheel studs. Place the wheel to the side.
5. Remove the two bolts that secure the brake caliper to the axle housing and then pull the caliper off the rotor. The brake pads will likely fall out of the caliper. Place the backside brake pad back into the caliper and discard the front side brake pad. You will use the backside brake pad to help push the piston back into the caliper.
6. Place a pair of vice grips over the backside brake pad and the backside of the caliper and squeeze the piston back into the caliper. Discard the old backside brake pad.
7. Place the new brake pads into the caliper. The brake pads rest inside grooved cutouts inside the caliper; they do not bolt into place.
8. Hold the pads in place as you slide the caliper back over the brake rotor.
9. Secure the caliper to the axle housing using the two bolts, socket and ratchet.
10. Place the tire back onto the Gallant an secure it to the wheel by threading the lug nuts onto the wheel studs. Give each lug nut a quarter turn using the tire iron.
11. Raise the Gallant with the jack until you can remove the jack stand. Lower the Gallant to the ground and tighten each lug nut using the tire iron.
12. Complete steps 2 through 11 for the passenger side brake.
13. Place the front cap back onto the master cylinder and close the engine hood.
