Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Loosen wheel lug nuts slightly before lifting the vehicle.

2. Lift the Vehicle

Use a jack to lift the vehicle and support it with jack stands.
Remove the front or rear wheels, depending on which brakes are grinding.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench
Remove the bolts securing the brake caliper using the socket set.
Carefully slide the caliper off the rotor. Support it with a bungee cord or rope to avoid straining the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check for uneven wear or glazing and replace if necessary.
Tools Required: Brake cleaner, wire brush
Clean the caliper bracket and rotor surface with brake cleaner and a wire brush if needed.
Install new brake pads, ensuring they are properly seated.

5. Inspect and Replace Brake Rotors (if necessary)

If rotors are worn or damaged, remove them from the hub.
Tools Required: Brake rotor puller (if applicable)
Install new rotors, ensuring they are properly aligned and secured to the hub.

6. Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (usually around 25-35 Nm).
Reinstall the wheel and torque the lug nuts to the specified value (usually around 110 Nm).

7. Final Checks

Pump the brake pedal to ensure the pads are seated properly.
Check the brake fluid level and add fluid if necessary.
