Solution

1. Preparation

Gather tools and parts. Ensure vehicle is on a level surface.
Tools Required: Floor jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.

2. Lift the Vehicle

Jack Up the Vehicle:
- Use the floor jack to lift the front or rear of the vehicle depending on which brakes are affected.
- Secure the vehicle with jack stands for safety.
Remove the Wheel:
- Use the lug wrench to remove the wheel nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; replace if less than 3mm.
Remove Brake Caliper:
- Use the socket set to remove caliper bolts. Support the caliper with a bungee cord or suitable hook to avoid stress on the brake line.
Replace Brake Pads:
- Remove the old pads and install new ones, ensuring they are properly seated.
Reassemble Caliper:
- Reattach the caliper securely and torque bolts to manufacturer specifications (typically around 25-30 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- Measure rotor thickness and inspect for any scoring. Replace if below minimum thickness or excessively worn.
Remove Rotors:
- If replacement is needed, remove any retaining screws and slide off the old rotor.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any manufacturing oil. Install it and secure with screws if applicable.

5. Final Checks and Reassembly

Brake Fluid:
- Check brake fluid level; top off if needed with DOT 4 fluid.
Reinstall Wheel:
- Place the wheel back on, hand-tighten the lug nuts, and then lower the vehicle.
Torque Lug Nuts:
- Once on the ground, torque the lug nuts to manufacturer specifications (usually around 100-120 Nm).
