Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, C-clamp, and OBD-II scanner.
Safety Warnings: Always ensure the vehicle is on a flat surface and securely supported by jack stands before working underneath.

2. Remove Wheel

Loosen the lug nuts slightly while the car is on the ground.
Use the jack to lift the vehicle 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 bolts using the socket set.
Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line; support it with a bungee cord or similar tool.
Inspect the brake pads for wear. If they are worn down to the metal, they need to be replaced.
Remove the old brake pads from the caliper bracket.
Insert new brake pads into the caliper bracket, ensuring they are aligned correctly.
Use a C-clamp to compress the caliper piston back into the caliper housing to make room for the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or scoring. If damaged, remove the rotor by unscrewing the retaining screws, if present.
Clean the hub surface with brake cleaner to ensure a good contact for the new rotor.
Install the new brake rotor, securing it with the retaining screws.
Ensure the rotor is free of oil or grease.

5. Reassemble the Brake Components

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer specifications (generally around 23-30 ft-lbs; consult a repair manual for exact specs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Finalize

Lower the vehicle off the jack stands using the jack.
Torque the lug nuts to the manufacturer’s specifications (usually around 75-90 ft-lbs).
Pump the brake pedal several times to ensure the pads are seated against the rotor.
