Solution

1. Preparation

Gather tools and parts needed, ensuring the vehicle is parked on a level surface.
Use wheel chocks to secure the vehicle.
Disconnect the battery (negative terminal) if working on electronic components.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel using a socket set.
- Inspect brake pads for uneven wear; measure thickness with a caliper.
- Check rotors for warping or scoring; use a dial indicator for precise measurements.
Replace Brake Pads:
- If worn unevenly, replace with new pads. Ensure they match OEM specifications.
- Clean the caliper and mounting bracket with brake cleaner.
- Apply anti-squeal lubricant to the back of the new pads.
Replace Rotors (if necessary):
- Remove caliper bracket bolts and slide off the caliper.
- Remove rotor screws (if applicable) and slide off the rotor.
- Install new rotor, ensuring it's seated properly.

3. Inspect Tires

Check Tire Pressure:
- Use a tire pressure gauge to ensure all tires are inflated to the manufacturer’s recommended pressure.
Inspect for Uneven Wear:
- Look for bald spots, cupping, or any unusual wear patterns. Replace tires as needed.
- Rotate tires to promote even wear if they are still usable.

4. Examine Suspension Components

Inspect Suspension:
- Check control arms, bushings, tie rods, and ball joints for play or damage using a pry bar.
- Replace any worn or damaged components.

5. Brake Fluid Check

Check and Replace Brake Fluid:
- Inspect the brake fluid reservoir for proper level; top off with the manufacturer-recommended brake fluid if low.
- If the fluid appears dark or contaminated, perform a brake fluid flush.
