Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Safety: Apply the parking brake and wear safety goggles.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor.
Remove old brake pads from the caliper bracket.
Inspect the caliper for damage; replace if necessary.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surfaces for grooves or warping.
If damaged, remove the rotor by unscrewing the retaining screws if present.
Install new rotors, applying anti-seize compound on the hub surface if needed.

5. Reassemble Braking Components

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer's specified torque (typically around 25-35 ft-lbs).
Replace wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Remove jack stands and lower the vehicle.
Fully tighten lug nuts in a crisscross pattern to the specified torque.
Pump the brake pedal a few times to ensure proper pad seating.
