Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the affected wheel using a socket set.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, socket set.

3. Inspect Components

Sub-steps:
1. Visually inspect the brake pads for uneven wear patterns.
2. Check the brake calipers for proper movement; ensure they are not seized.
3. Inspect the brake rotors for any signs of warping or scoring.
4. Look for any signs of contamination on brake pads and rotors.
Tools Required: Flashlight, inspection mirror.

4. Replace Brake Pads (if needed)

Sub-steps:
1. Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Install new brake pads in the caliper bracket.
4. Compress the caliper piston using a brake caliper tool to allow room for the new pads.
5. Reposition the caliper over the new pads and secure with bolts to the specified torque (typically 25-35 ft-lbs).
Tools Required: Socket wrench, brake caliper tool, torque wrench.

5. Reassemble and Test

Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and then fully tighten the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
3. Reconnect the battery and perform a brake test in a safe area.
Tools Required: Torque wrench.
