Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface.
Disconnect the battery to avoid any electrical issues during repair.

2. Remove Wheels

Using a lug wrench, loosen the lug nuts on the front wheels.
Jack up the vehicle and secure it on jack stands.
Remove the wheels completely.

3. Inspect and Replace Brake Rotors

Inspection: Measure rotor thickness using a micrometer. If below specifications or warped, proceed to replace.
Removal: Unbolt the caliper bracket and remove the brake caliper. Hang the caliper using a bungee cord to avoid straining the brake line.
Rotor Removal: Remove the rotor by unbolting it from the hub or sliding it off if not bolted.
Installation: Install new rotors, ensuring they are seated properly. Torque bolts to manufacturer's specifications (typically around 80-100 ft-lbs).

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads, ensuring they are correctly oriented and seated.

5. Reassemble and Test

Reattach the brake caliper over the new pads and torque bolts to specifications.
Reinstall the wheels and torque lug nuts in a criss-cross pattern.
Lower the vehicle and reconnect the battery.
Test the brake system by lightly applying brakes and checking for any issues.
