Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

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 Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if they are below 3mm, replacement is necessary.
- Look for any uneven wear or damage.
Replace Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the rotor and support it using a bungee cord to avoid straining the brake line.
- Remove old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Brake Rotors:
- Check for any visible scoring, cracks, or warping.
Replace Brake Rotors:
- If replacement is necessary, remove the retaining screws (if applicable) and slide the rotor off the hub.
- Install the new rotor onto the hub, securing it with screws.

5. Reassemble Components

Reinstall the caliper over the new brake pads and rotor.
Tighten caliper bolts to manufacturer’s specifications (typically 25-35 ft-lbs).
Reinstall the wheel and tighten lug nuts in a star pattern to ensure even pressure.

6. Final Checks

Reconnect the battery and check brake fluid level, adding fluid if needed.
Test the brake pedal for firmness before lowering the vehicle.
