Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, wire brush, jack and jack stands.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect: Check the brake pads for thickness; replace if they are less than 3mm thick.
Remove: Unbolt the caliper using the socket set and slide it off the rotor.
Replace: If pads are worn, remove them from the caliper bracket. Install new brake pads ensuring they are properly positioned.

4. Clean and Inspect Rotors

Use a wire brush to clean any rust or debris from the rotor surface.
Inspect the rotor for grooves, cracks, or excessive wear; replace if necessary.
If rotors are in good condition, clean them thoroughly with brake cleaner.

5. Reassemble Components

Reattach the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer’s specified torque (typically around 25-35 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands.
Torque the lug nuts to the specified value (typically around 120 Nm).
Pump the brake pedal a few times to ensure proper brake engagement.
