Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the vehicle from power by putting it in service mode and disabling the parking brake.

2. Lift the Vehicle

Tools Required: Floor jack, jack stands
Use the floor jack to lift the front or rear of the vehicle as needed.
Securely place jack stands under the vehicle for safety.

3. Remove the Wheel

Tools Required: Lug wrench
Loosen and remove the lug nuts using the lug wrench.
Remove the wheel to access the brake assembly.

4. Remove the Brake Caliper

Tools Required: Socket set, torque wrench
Remove the caliper mounting bolts using the socket set.
Carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or strap to avoid straining the brake line.

5. Inspect and Replace Brake Pads

Inspect the existing brake pads for wear indicators and thickness.
If replacement is necessary, remove the old pads from the caliper bracket.
Insert new brake pads into the bracket, ensuring they are properly aligned.
Parts Required: New brake pads

6. Reassemble the Brake Assembly

Slide the brake caliper back over the new pads and rotor.
Reinstall the caliper mounting bolts and torque them to the manufacturer's specifications (typically around 25-35 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove the jack stands and lower the vehicle using the floor jack.
Tighten the lug nuts to the manufacturer's torque specifications (usually around 100-110 ft-lbs).

8. Final Checks

Reconnect the vehicle power if previously disconnected.
Test the brakes by pressing the pedal several times to ensure proper engagement.
