Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as necessary.
Secure the vehicle with jack stands.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect:
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and suspend it using a bungee cord to avoid stress on the brake line.
- Check the thickness of the brake pads; if they are below 3mm, replace them.
Replace:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.
- Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).

5. Inspect and Replace Brake Rotors (if needed)

Inspect:
- Check rotors for scoring, grooves, or warping; replace if any damage is found.
Replace:
- Remove the caliper bracket by taking off the bolts.
- Slide the rotor off the hub; if stuck, gently tap with a rubber mallet.
- Clean the hub surface and install the new rotor, ensuring it is properly aligned.
- Reattach the caliper bracket and torque bolts to manufacturer specifications.

6. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the correct specification (typically 100-120 ft-lbs).

7. Test Brake System

Pump the brakes a few times to ensure pads seat properly against the rotors.
Check brake fluid level and top off if necessary.
