Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, wire brush, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the negative battery terminal to avoid electrical issues.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are grinding.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Take off the wheel to access the brake components.

4. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the socket set.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for thickness and wear. Replace if they are below the manufacturer's minimum thickness (usually 3mm).
Brake Rotors:
- Check the rotors for grooves, scoring, or warping. Replace if necessary.
Brake Calipers:
- Inspect the caliper for signs of sticking or damage. Clean the caliper slides if necessary.

5. Replace Components

If Brake Pads are Worn:
- Remove the old pads and install new ones, ensuring proper alignment.
If Rotors are Damaged:
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub. Install the new rotor, ensuring it is properly seated.
Reassemble:
- Reinstall the caliper over the new pads or rotor and tighten the caliper bolts to the manufacturer's torque specifications.

6. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground using the jack and remove jack stands.
Torque the lug nuts to the manufacturer's specifications.

7. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to restore brake pressure before driving.
