Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle using a jack and secure it on jack stands.
Remove the wheel corresponding to the grinding brake.

2. Inspect and Remove Brake Pads

Sub-steps:
- Use a socket set to remove the caliper bolts.
- Carefully slide the caliper off the rotor and support it without straining the brake line.
- Remove the brake pads from the caliper bracket.
- Inspect the pads for thickness; they should be at least 1/8 inch thick.
- Tools Required: Socket set, torque wrench, brake pad spreader.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotor surface for grooves or warping using a straightedge.
- If damaged, remove the rotor by unbolting it from the hub.
- Install new rotors, ensuring they are properly seated against the hub.
- Tools Required: Impact wrench (if available), brake cleaner.

4. Install New Brake Pads

Sub-steps:
- Apply brake grease to the backing of new pads (avoid contact with the friction surface).
- Insert new pads into the caliper bracket.
- Reinstall the caliper over the new pads and torque the bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).
- Tools Required: Torque wrench.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and lower the vehicle.
- Pump the brake pedal a few times to seat the pads against the rotor.
- Test drive the vehicle at low speeds to ensure brakes function correctly.
- Safety Warnings: Ensure no tools are left near the brakes; check for leaks before test driving.
