Solution

1. Preparation

Tools Required: Socket set, jack stands, brake cleaner, lug wrench.
Begin by parking the vehicle on a level surface and engaging the parking brake for safety.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove Wheel

Use the lug wrench to loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, brake pad spreader.
Remove the caliper by unbolting it from the bracket.
- Sub-steps:
  - Use a socket set to remove the caliper bolts.
  - Carefully hang the caliper using a bungee cord to avoid straining the brake line.
Inspect the brake pads for thickness; replace if less than 3mm.
- Sub-steps:
  - Remove the old brake pads from the caliper bracket.
  - Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotors for any grooves or scoring. Replace if necessary.
- Sub-steps:
  - Unbolt the rotor from the hub.
  - Install the new rotor and torque the bolts to manufacturer specifications (typically 80-100 ft-lbs).

5. Reassemble Braking System

Reattach the caliper over the new brake pads.
- Sub-steps:
  - Tighten the caliper bolts to the manufacturer’s torque specifications.
  - Ensure all components are correctly aligned and secured.

6. Reinstall Wheel and Final Checks

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually 76-80 ft-lbs).
Reconnect the battery.
