Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Disconnect the battery to prevent electrical issues during the repair.

2. Inspect and Replace Brake Rotors

Remove the wheel: Use a lug wrench to loosen and remove the lug nuts. Lift the vehicle using a jack and secure it with jack stands.
Remove the brake caliper: Use a socket set to unbolt the caliper from the bracket. Hang the caliper using a zip tie or bungee cord to avoid straining the brake line.
Remove the brake rotor: Remove any retaining screws (if applicable) and slide the rotor off the hub.
Inspect the rotor: Check for warping or scoring. If warped, replace with new rotors.
Install new rotor: Place the new rotor onto the hub, ensuring it's seated correctly.

3. Replace Brake Pads

Remove old brake pads: Slide the old pads out of the caliper bracket.
Install new brake pads: Place new pads in the caliper bracket, ensuring they are properly aligned.
Reattach the caliper: Position the caliper over the new pads and secure it using the bolts. Torque to manufacturer specifications (typically 20-30 Nm).

4. Reassemble and Test

Reinstall the wheel: Place the wheel back on, hand-tighten the lug nuts, then lower the vehicle.
Torque lug nuts: Use a torque wrench to tighten the lug nuts to the manufacturer's specifications (usually around 110 Nm).
Reconnect battery: Reconnect the battery terminals.
Test brake function: Before driving, pump the brake pedal a few times to seat the pads against the rotors.
