Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is on a flat surface and securely lifted.
Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket.
Carefully slide the caliper off the rotor and support it using a bungee cord or similar device (do not hang it by the brake line).
Inspect the brake pads for wear. If the pads are worn down to the metal backing or below the manufacturer's wear indicators, replace them.
Remove the old pads from the caliper bracket and install new pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or warping. If damaged, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Clean the hub surface with brake cleaner to ensure proper seating of the new rotor.
Install a new rotor, ensuring it is flush against the hub.

5. Reassemble Brake Components

Slide the caliper back over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque value (typically around 25-35 lb-ft, but verify in the service manual).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle back to the ground and fully tighten the lug nuts to the specified torque (usually 100-120 lb-ft).
Pump the brake pedal a few times to ensure proper brake engagement before driving.
