Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Wear safety goggles and gloves for protection.

2. Inspect and Replace Brake Pads and Rotors

Loosen Lug Nuts: Use a lug wrench to slightly loosen the lug nuts on the front wheels.
Raise Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheels: Completely remove the lug nuts and take off the front wheels.
Inspect Brake Pads: Remove the caliper bolts using a socket wrench, then slide the caliper off. Check the brake pads for thickness and wear.
Inspect Rotors: Measure the rotor thickness using a caliper; if below the minimum specification or warped, replace them.
Replace Brake Pads: If worn, replace the brake pads with new ones, ensuring they are properly seated in the caliper bracket.
Replace Rotors: If necessary, remove the rotor by unscrewing the retaining screws (if applicable) and install the new rotor.
Reassemble: Reattach the caliper and tighten the caliper bolts to the manufacturer’s specifications.

3. Check Wheel Alignment and Balance

Inspect Tires: Check for uneven wear and ensure tires are inflated to the recommended pressure.
Align Wheels: Take the vehicle to a professional alignment shop to ensure proper alignment of the wheels.
Balance Tires: Have the tires balanced if they show signs of vibration or uneven wear.
