Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Remove the brake caliper by unscrewing the caliper bolts using a socket set.
Lift the caliper away from the rotor and suspend it using a wire or bungee cord (do not let it hang by the brake line).
Inspect brake pads for excessive wear or burning; replace if necessary.
Check the rotor surface for damage or overheating signs; replace if warped or scored.

4. Replace Brake Pads/Rotors (if necessary)

If brake pads are worn, remove them from the caliper bracket.
Install new brake pads by sliding them into the bracket.
If rotors are damaged, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install the new rotor and torque retaining screws as per manufacturer specifications.

5. Reassemble Components

Reattach the brake caliper over the new pads or rotor.
Secure the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specifications.

6. Final Checks

Refill or bleed the brake fluid system if necessary.
Test the brake pedal feel and ensure it feels firm.
Check for any leaks around the brake components.
