Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and eyewear.

2. Inspect and Replace Brake Pads and Rotors

Remove the wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect brake components:
- Check the brake pads for thickness; replace if worn down past the indicator.
- Examine rotors for scoring, pitting, or warping using a dial indicator.
Replace if necessary:
- If rotors are warped, replace them with new rotors. Clean the hub surface before installation.
- Install new brake pads; ensure they are correctly positioned and lubricate the backing plates with anti-seize compound.

3. Check Suspension and Alignment

Inspect suspension components:
- Check for any loose or damaged parts such as tie rods, control arms, and bushings.
- Tighten any loose bolts to manufacturer specifications.
Align wheels:
- If the alignment is off, take the vehicle to a professional alignment shop for adjustments.

4. Check and Replace Tires if Necessary

Inspect tires:
- Check for uneven wear patterns, bulges, or other damage. Replace tires if necessary.
Inflate tires:
- Ensure all tires are inflated to the manufacturer’s specified pressure.
