Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Raise the Vehicle

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

3. Remove Wheel

Use a socket set to remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspection:
- Check the brake pads for wear indicators. If less than 3mm thick, they need replacement.
Replacement:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and suspend it without straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-35 Nm).

5. Inspect and Resurface or Replace Rotors

Check rotor surface for scoring or warping.
If warped, either resurface or replace the rotors.
Clean the rotor surface with brake cleaner before reassembly.

6. Reassemble and Test

Reattach the wheel and torque the lug nuts to specifications (around 100 Nm).
Lower the vehicle and pump the brake pedal to restore brake pressure.
Test the brakes at low speed for any noise or abnormal operation.
