Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Inspect and Replace Brake Pads

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, and new brake pads.
Sub-steps:
1. Loosen the lug nuts on the front wheels while the vehicle is on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the front wheels.
4. Inspect the brake pads for thickness; replace if below the manufacturer's recommended minimum (typically 3mm).
5. Remove the caliper bolts and lift the caliper off the rotor.
6. Replace the brake pads, ensuring they are correctly positioned and seated.
7. Reattach the caliper and torque bolts to the manufacturer's specifications.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, socket set, brake cleaner.
Sub-steps:
1. If rotors are warped or damaged, remove them by unscrewing the retaining screws or bolts.
2. Clean the hub surface with brake cleaner before installing new rotors.
3. Install new rotors and ensure they are seated properly.
4. Reattach the caliper and torque bolts to the manufacturer's specifications.

4. Wheel Alignment and Balance

Tools Required: Alignment machine (usually handled by a shop).
Sub-steps:
1. After replacing brake components, take the vehicle to a professional alignment shop.
2. Request a four-wheel alignment and balance check.
3. Confirm that specifications meet manufacturer recommendations.
