Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual check.
2
Check the condition of the brake rotors for grooves or scoring.
3
Examine brake calipers for proper movement and any signs of leakage.
4
Inspect brake fluid level and condition in the master cylinder.
5

Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, brake cleaner, new brake pads, new rotors (if necessary), and safety equipment (gloves, goggles).
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Loosen the lug nuts on the wheel where the grinding noise is occurring.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts using the socket set.
- Carefully slide the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
- Clean the caliper bracket with brake cleaner.
- Install new brake pads into the bracket.
Brake Rotors (if necessary):
- If rotors are scored or warped, remove the rotor by unscrewing any retaining screws and pulling it off the hub.
- Clean the hub surface.
- Install the new rotor, ensuring it is seated properly.
Caliper Reassembly:
- Compress the caliper piston using a caliper tool to fit over the new pads.
- Reinstall the caliper over the new pads and rotor.
- Tighten caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).

4. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer’s specification (typically 75-85 ft-lbs).
Reconnect the negative battery terminal.
Start the vehicle and pump the brakes to ensure proper pad seating.
