Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery if necessary.
Safety glasses and gloves should be worn.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Assembly

Tools Required: Wrench set, socket set
Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the brake rotor; support it with a bungee cord to avoid straining the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect Components

Check the brake rotor for scoring or warping; replace if necessary.
Inspect the caliper for proper movement; clean and lubricate the caliper slides if they are sticking.
Examine the brake hardware for wear; replace shims and clips if damaged.

5. Install New Brake Pads

Parts Required: New brake pads
Position the new brake pads into the caliper bracket.
Ensure they are seated properly and align with the rotor.

6. Reinstall Brake Assembly

Slide the caliper back over the new brake pads and rotor.
Reinstall and torque the caliper bolts to the manufacturer specifications (typically around 20-25 ft-lbs).

7. Reinstall Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs).
