Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor and suspend it using a bungee cord (do not let it dangle by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of damage or wear.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or excessive wear.
If needed, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor and torque to manufacturer specifications (typically around 80-100 ft-lbs).

5. Reassemble Braking Components

Reattach the caliper over the new brake pads and rotor.
Secure the caliper bolts to the manufacturer’s torque specification (typically around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification (typically around 80-100 ft-lbs).

6. Final Checks

Pump the brake pedal to ensure the brakes are seated properly.
Test the brake system for proper function before driving.
