Solution

1. Preparation

Gather tools and parts required for the repair.
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 wheel bolts using a socket set and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection: Visually check the brake pads for wear. If the thickness is less than 3mm, replacement is necessary.
Replacement:
1. Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Install new brake pads, ensuring they are properly seated in the caliper bracket.
4. Reattach the caliper over the new pads, tightening the bolts to the manufacturer’s specified torque (typically around 25-35 Nm).

4. Check and Replace Brake Rotors (if needed)

Inspect the rotors for grooves or excessive wear.
If replacement is required:
1. Remove any retaining screws on the rotor.
2. Slide off the old rotor and clean the hub surface.
3. Install the new rotor, securing it with screws as necessary.

5. Reassemble and Recheck

Reinstall the wheel and hand-tighten the bolts.
Lower the vehicle and tighten the wheel bolts to the manufacturer's specified torque (typically around 120-140 Nm).
Reconnect the negative battery terminal.
