Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Measure rotor thickness using a micrometer.
- If rotors are warped (more than 0.002 inches runout), replace them.
- Clean rotors with brake cleaner if reusing.
Replace Brake Pads:
- Remove the caliper by unscrewing the caliper bolts.
- Slide off the caliper and support it without stressing the brake line.
- Remove old brake pads and install new pads ensuring proper orientation.
Install New Rotors:
- If replacing, remove the old rotors and install new ones.
- Torque rotor retaining screws to manufacturer specifications.

4. Reassemble Components

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a criss-cross pattern.

5. Final Checks

Reconnect the negative battery terminal.
Lower the vehicle and perform a final torque check on lug nuts.
