Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Lift the caliper away from the rotor and secure it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads, noting their orientation.
Install new brake pads, ensuring they are correctly positioned and seated.

4. Inspect and Resurface/Replace Rotors

Remove the rotor by unscrewing the retaining screws (if applicable).
Inspect the rotor for warping or excessive wear.
If warped, either have the rotor resurfaced or replace it with a new one.
Reinstall the rotor, ensuring it is secured properly.

5. Reassemble and Tighten Components

Reattach the brake caliper, ensuring it is properly seated over the new pads.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-35 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications (typically 100-120 Nm).
Reconnect the battery.
