2
Check brake rotors for scoring, warping, or damage.
3
Examine brake calipers for proper function and alignment.
4

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Use wheel chocks to prevent movement.
Disconnect the battery to ensure safety while working on the brakes.

2. Remove Wheel

Loosen the lug nuts on the wheel using a socket set.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect the brake pads for wear; if they are below the manufacturer's specified thickness, replace them.
Use a brake pad spreader or C-clamp to retract the caliper piston.
Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor and support it without putting stress on the brake line.
Remove the old brake pads and install new pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping. Replace if damaged.
Remove the rotor by unscrewing the retaining screws or sliding it off the hub.
Install new rotors, ensuring they are clean and free of grease.
Apply anti-seize compound on the hub to prevent future corrosion.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified torque value.

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to ensure proper brake pad seating.
Test drive the vehicle to confirm the grinding noise is resolved.
