Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Remove the Wheel

Tools Required: Socket set, torque wrench.
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

Tools Required: Socket set, brake caliper tool.
Remove the caliper mounting bolts using the socket set.
Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid stress on the brake line.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if below the manufacturer's specification, replace them.
Sub-steps:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply anti-squeal grease to the backing of the new pads.
- Install the new brake pads into the caliper bracket.

5. Inspect and Replace Brake Rotor

Check the rotor surface for damage; if warped or excessively grooved, replace it.
Sub-steps:
- Remove the rotor by unscrewing the rotor retaining screws (if applicable).
- Install the new rotor onto the hub and secure it.

6. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper mounting bolts to the manufacturer's torque specifications (usually around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Checks

Lower the vehicle from jack stands and tighten the lug nuts to the specified torque (typically 100-120 Nm).
Pump the brake pedal to seat the new pads against the rotors.
