Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Lift the vehicle using the jack and support it securely with jack stands.
3. Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors (if warped)

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the brake caliper by unbolting it and securing it away (do not let it hang by the brake line).
2. Remove the brake pads from the caliper bracket.
3. Measure the thickness of the rotors; if below the minimum specification or warped, replace them.
4. If replacing, remove the rotor by unbolting it from the hub.
5. Install new rotors, ensuring they are properly seated.

4. Install New Brake Pads

Tools Required: Caliper tool (if needed), lubricant.
Sub-steps:
1. Apply brake lubricant to the backing plate of the new brake pads to prevent noise.
2. Install the new brake pads into the caliper bracket.
3. Reinstall the caliper over the new pads and secure it with bolts to the specified torque.

5. Reassemble and Test

Tools Required: Lug wrench, jack, jack stands.
Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands and tighten the lug nuts to the manufacturer's specified torque.
3. Pump the brake pedal several times to seat the pads against the rotors.
4. Check brake fluid level and top off if necessary.
