Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
Safety: Disconnect the vehicle's battery to prevent any electrical issues while working.

2. Inspect and Replace Brake Components

Lift the Vehicle
- Use a jack to raise the vehicle and secure it with jack stands.
- Tools: Floor jack, jack stands.
Remove Wheel
- Use a socket set to remove the lug nuts and take off the wheel.
- Tools: Socket set, impact wrench (if available).
Inspect Brake Rotors
- Check for warping or uneven wear on the rotors using a dial indicator.
- If warping is detected (more than 0.002 inches), replace the rotors.
- Tools: Dial indicator, micrometer.
Inspect Brake Pads
- Examine the brake pads for thickness. Replace if they are below the manufacturer's specifications (usually 3mm or less).
- Clean the caliper and pad surfaces.
- Tools: Brake pad gauge, cleaning brush.
Reassemble
- If components are replaced, install new rotors and pads.
- Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).
- Tools: Torque wrench.

3. Wheel Alignment and Balance

Check Wheel Alignment
- Use an alignment tool or take the vehicle to a shop for a professional alignment.
- Ensure all angles (caster, camber, toe) are within specifications.
Balance Wheels
- If the wheels are out of balance, have them balanced using a wheel balancing machine.
