Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
If applicable, disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Brake Pads

Remove Wheel:
- Use a jack to lift the vehicle and secure it on jack stands.
- Use a socket set to remove the lug nuts and take off the wheel.
Remove Brake Caliper:
- Use a socket wrench to remove the caliper bolts.
- Carefully lift the caliper off the rotor without stretching the brake line.
Inspect Brake Pads:
- Check the thickness of the brake pads. If less than 3mm, they need replacement.
- Look for uneven wear or glazing on the pads.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket, ensuring they fit snugly.

3. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition:
- Inspect the rotors for grooves, rust, or warping.
- If damaged beyond repair, proceed to replace.
Remove Rotors:
- If needed, remove the retaining screws and slide the rotor off the hub.
Install New Rotors:
- Place new rotors onto the hub and secure with retaining screws (if applicable).

4. Reassemble Braking System

Reattach Brake Caliper:
- Carefully position the caliper back onto the rotor and secure with bolts, using specified torque values (usually around 25-30 Nm).
Reinstall Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to manufacturer specifications.

5. Final Checks

Reconnect the battery if it was disconnected.
Check brake fluid level and top off if necessary.
