Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, caliper tool, socket set.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel using a lug wrench.

2. Inspect and Remove Brake Components

Inspect Brake Pads:
- Remove the brake caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
- Remove the brake pads from the caliper bracket.
Inspect Brake Rotors:
- Check for any rust, scoring, or warping on the rotors.
- If necessary, remove the rotor by unscrewing the retaining screws or using a hammer to gently tap it off.

3. Replace Brake Pads and/or Rotors

If Brake Pads Are Worn:
- Install new brake pads ensuring they are properly seated in the caliper bracket.
If Rotors Are Damaged:
- Replace with new rotors, ensuring they are clean and free from debris.
- Torque the rotor retaining screws to manufacturer specifications.

4. Reassemble Braking System

Reattach the brake caliper over the new pads and rotors.
Tighten caliper bolts to the manufacturer's torque specifications.
Reinstall the wheel and torque the lug nuts to the specified value.

5. Test the Braking System

Lower the vehicle from the jack stands.
Pump the brake pedal to ensure proper function and seating of the brake pads.
Conduct a test drive to check for grinding noises and ensure braking performance is restored.
