Solution

1. Preparation

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

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts slightly.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket wrench.
Carefully hang the caliper using a bungee cord to avoid stressing the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing for any wear indicators; replace if worn down.
Install new brake pads into the caliper bracket, ensuring they are oriented correctly.

4. Check and Replace Brake Rotors (if necessary)

Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Inspect the rotor for warping or scoring. Replace if any damage is noted.
Clean the hub surface with a wire brush to ensure proper contact.
Install the new rotor, ensuring it is securely fastened.

5. Reassemble Brake Components

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque value (usually around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle and remove jack stands.
Tighten the lug nuts to the specified torque value (usually around 100-120 Nm).
Test the brakes by applying them gently to ensure proper function and check for any noise.
