Solution

1. Preparation

Gather all necessary tools and parts.
Safely park the vehicle on a level surface and set the parking brake.
Place wheel chocks behind the rear tires.
Gather safety equipment including gloves and safety glasses.

2. Remove Wheel

Loosen lug nuts using a socket wrench.
Raise the vehicle with a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper and bracket for any damage or rust.
If needed, replace the brake pads with new ones, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the thickness of the rotor with a micrometer. If below minimum specifications, replace the rotor.
Remove the rotor by unscrewing the retaining screws (if applicable) or pulling it off the hub.
Clean the hub surface and install the new rotor, ensuring it is properly seated.

5. Reassemble Braking System

Reinstall the caliper over the new brake pads and rotor.
Secure the caliper by tightening the caliper bolts to the manufacturer's specified torque (typically around 20-30 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from jack stands and remove the jack.
Tighten lug nuts to the specified torque (typically around 100-150 lb-ft).
Pump the brake pedal several times to ensure proper caliper function and pad seating.
