Solution

1. Preparation

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

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using the jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench and slide the caliper off the rotor.
Tools Required: Socket set.
Support the caliper using a bungee cord or suitable method to avoid stressing the brake line.
Check the brake pads for wear; replace if they are worn down to 3mm or less.
Remove old pads and install new brake pads, ensuring they are positioned correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Examine the rotors for deep grooves or excessive wear. If damaged, remove the rotor by unscrewing the retaining screws or caliper bracket, if applicable.
Tools Required: Torque wrench for reinstallation.
Replace with new rotors, ensuring they are clean of any oil or debris.
Torque the rotor screws to the manufacturer's specified value (usually around 80-100 ft-lbs depending on the model).

5. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Carefully lower the vehicle and remove the jack stands.
Tighten the lug nuts to the manufacturer’s specified torque (usually around 76 ft-lbs).
Start the vehicle and pump the brakes a few times to ensure proper operation.
Test drive the vehicle at low speeds to confirm the grinding noise has been resolved.
