Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves.

2. Raise the Vehicle

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

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Keep lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Pads

Inspect: Remove the caliper bolts using a socket set and take off the caliper to access the brake pads.
Replace: If pads are worn down (less than 3mm), replace them with new ones.
- Tools Required: Socket set, brake pad spreader.
- Parts Required: New brake pads.

5. Inspect and Replace Brake Rotors (if needed)

Check the rotors for signs of damage or excessive wear.
If warped or scored, replace them:
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, ensuring it's seated properly.
- Tools Required: Torque wrench, rotor removal tool.
- Parts Required: New brake rotors.

6. Reassemble Brakes

Reattach the caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (refer to service manual for torque values).
Reinstall the wheel and tighten lug nuts in a crisscross pattern to ensure even tightening.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
