Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lift it using a jack and jack stands.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel and Brake Components

Use a lug wrench to loosen the lug nuts and remove the wheel.
Remove the brake caliper bolts using a socket set.
Carefully slide the caliper off the rotor. Support it using a bungee cord or hang it to avoid stressing the brake line.
Remove the brake pads from the caliper bracket.

3. Inspect and Replace Components

Brake Pads: Check for thickness. If less than 3mm, replace with new pads.
Brake Rotors: Measure rotor thickness and inspect for grooves. If worn beyond specifications or damaged, replace rotors.
Calipers: Check for fluid leaks and proper movement. Replace if damaged.

4. Install New Components

Install new brake pads into the caliper bracket.
If rotors are replaced, install new rotors onto the hub.
Reattach the brake caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specification (usually around 25-30 Nm).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specification (typically 100-120 Nm).
Reconnect the battery.
Pump the brake pedal to ensure proper seating of the pads.
Test drive to confirm the grinding noise is resolved and that braking performance is restored.
