Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to eliminate any electrical hazards.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, brake cleaner, wire brush
Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts.
2. Support the caliper with a bungee cord or similar method to avoid straining the brake line.
3. Remove old brake pads from the caliper bracket.
4. Clean the caliper and bracket with brake cleaner and a wire brush.
5. Install new brake pads, ensuring they are properly aligned in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if rotors are stuck), torque wrench
Sub-steps:
1. Check the rotor for grooves or uneven wear.
2. If replacement is needed, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
3. Install new rotors, ensuring the surface is clean and free of contaminants.
4. Torque the retaining screws to the manufacturer’s specifications.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reattach the caliper over the new brake pads and torque the caliper bolts to the specified value.
2. Reinstall the wheel, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts in a crisscross pattern.
3. Reconnect the battery and check for any error codes.
