Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and is in gear (or in 'Park' for automatic).
Disconnect the battery to prevent electrical issues during the repair.

2. Remove Wheel

Use a jack to lift the vehicle securely.
Remove lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Check brake pads for wear; if they are below 3mm in thickness, they need replacement.
Replace:
1. Remove the caliper bolts with a socket wrench.
2. Carefully slide the caliper off the rotor.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are oriented correctly.
5. Reinstall the caliper over the new pads and tighten the bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are worn or damaged, remove them:
1. Remove any retaining screws or clips holding the rotor in place.
2. Slide the rotor off the wheel hub.
3. Install new rotors by reversing the removal steps.
4. Torque the retaining screws to manufacturer specifications.

5. Reassemble and Test

Reattach the wheel and tighten the lug nuts in a crisscross pattern.
Lower the vehicle and reconnect the battery.
Pump the brake pedal a few times to ensure proper brake engagement.
