Diagnostic Steps

1
Inspect brake pads for wear; measure thickness and look for uneven wear.
2
Check brake rotors for scoring, warping, or rust buildup.
3
Inspect brake calipers for proper operation and signs of leakage.
4
Examine brake fluid level and condition in the master cylinder reservoir.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a socket set to loosen and remove the lug nuts.
Carefully lift the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it using a bungee cord (do not let it hang from the brake line).
- Remove the old brake pads from the caliper bracket.
Replace Brake Pads:
- Install new brake pads, ensuring they fit snugly in the caliper bracket.
- Apply brake grease to the back of the pads (if recommended by the manufacturer).
- Reinstall the caliper over the new pads and secure it with the caliper bolts to the specified torque (typically 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove them by unbolting the rotor from the hub.
Clean the hub surface and install new rotors.
Ensure rotors are torqued to the manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (usually 100-120 ft-lbs).
Reconnect the battery.
Start the vehicle and pump the brakes to ensure proper pad seating.
Test drive at low speeds to verify that the grinding noise has been resolved.
