Solution

1. Preparation

Gather tools: socket set, torque wrench, brake cleaner, and a jack.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to avoid electrical issues during repairs.

2. Wheel Removal

Loosen lug nuts on the affected wheel while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Pad and Rotor Inspection

Visual inspection: Check brake pads for wear indicators; replace if worn down to less than 3mm.
Inspect brake rotors for any grooves or uneven surfaces; replace if damaged.
If the pads or rotors are worn, proceed to replace them.

4. Brake Pad Replacement

Remove the caliper by unscrewing the caliper bolts.
Slide the caliper off the rotor and hang it with a wire to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new pads to reduce noise and install them.

5. Rotor Replacement

If necessary, remove the retaining screws and slide off the old rotor.
Clean the hub surface with brake cleaner, ensuring no debris remains.
Install the new rotor, securing it with screws.

6. Reassemble Brake Components

Reattach the caliper over the new pads and rotor, ensuring it seats properly.
Torque caliper bolts to the manufacturer's specifications (usually around 20-30 Nm).
Reinstall the wheel and torque the lug nuts to the recommended specification.

7. Final Checks

Reconnect the battery and check the brake fluid level, topping up if necessary.
Test the brakes by pressing the pedal a few times to seat the new pads.
