Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Brake Components

Remove the Wheel:
- Loosen lug nuts with a socket wrench.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Pads and Rotors:
- Remove the brake caliper by loosening the bolts with a socket wrench.
- Slide the caliper off the rotor, being careful not to damage the brake line.
- Remove the brake pads and measure their thickness; replace if they are worn beyond specifications (usually less than 3mm).
- Inspect the brake rotor for warping or scoring; replace if warped (check for runout with a dial indicator).
Replace Brake Components:
- If necessary, install new brake pads and rotors.
- Reassemble the caliper and tighten the bolts to the manufacturer's torque specifications (typically around 25-35 ft-lbs).

3. Wheel Alignment and Balancing

Check Wheel Alignment:
- Inspect the alignment of the front wheels and adjust if necessary using an alignment machine.
- Ensure the suspension components are intact and replace any damaged parts.
Balance Tires:
- Remove the tires and take them to a tire shop for balancing.
- Reinstall the tires on the vehicle.
