Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench.
Take off the wheel to access the brake assembly.

3. Inspect Brake Components

Brake Pads:
- Check thickness; replace if less than 3mm.
- Look for uneven wear or cracking.
Brake Rotors:
- Inspect for grooves, scoring, or warping; replace if needed.
Brake Calipers:
- Check for proper movement and any signs of leakage; service or replace if necessary.

4. Replace Brake Pads and Rotors (if necessary)

Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated properly.
Brake Rotors:
- If replacing, remove the old rotor by unscrewing the retaining screws.
- Install the new rotor, ensuring it is flush against the hub.

5. Reassemble Components

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer’s specifications (typically around 25-35 Nm).
Reattach the wheel and lug nuts, tightening to the specified torque (usually around 90-110 Nm).

6. Test Brakes

Lower the vehicle and perform a test of the brakes by gently applying them to ensure proper function and listen for noise.
