Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery for safety, especially if working on the electrical components of the braking system.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts using a socket wrench.
2. Raise the vehicle using a jack and secure it on jack stands.
3. Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor, ensuring not to damage the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Measure the thickness of the new brake pads against specifications.
5. Install the new brake pads into the caliper bracket.
6. Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer's torque specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Remove the caliper bracket if the rotor needs to be replaced.
2. Unscrew the rotor retaining screws (if applicable) and slide the rotor off the hub.
3. Clean the hub surface and install the new rotor, ensuring it is properly seated.
4. Reattach the caliper bracket and tighten bolts to the specified torque.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands.
3. Torque the lug nuts to the specified value.
4. Reconnect the battery if disconnected.
5. Pump the brake pedal several times to seat the brake pads properly.
