Solution

1. Preparation

Gather all tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Lift the Vehicle

Use a hydraulic jack to raise the front or rear of the vehicle, depending on where the grinding is occurring.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Keep the lug nuts in a safe place for reinstallation.

4. Inspect the Brake Components

Remove the brake caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads for wear; if they are less than 3mm thick or show uneven wear, they need to be replaced.
Check the brake rotor for scoring or grooves; if damaged, it should be resurfaced or replaced.

5. Replace Brake Pads and Rotors

If replacing pads:
- Compress the brake caliper piston using a brake tool or C-clamp to create space for new pads.
- Install new brake pads in the caliper bracket.
If replacing rotors:
- Remove the retaining screws (if equipped) and slide the old rotor off.
- Place the new rotor on the hub, ensuring it is seated correctly.

6. Reassemble Components

Reinstall the brake caliper over the new pads/rotor and tighten caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Reattach the wheel and secure with lug nuts (torque to manufacturer specifications, typically 76-84 ft-lbs).

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Reconnect the battery.
