Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Wear safety glasses and gloves.

2. Inspect Brake Components

Tools Required: Jack and jack stands, lug wrench, torque wrench, socket set.
Raise the front of the vehicle using a jack, secure it with jack stands.
Remove the front wheels using a lug wrench.
Inspect brake pads for thickness (should be at least 3mm) and replace if worn.
Check rotors for grooves or scoring; replace if necessary.

3. Check Rotor Warpage

Tools Required: Dial indicator.
Secure the dial indicator to the brake caliper.
Rotate the rotor and observe the dial for any runout (should be within manufacturer specifications, usually less than 0.002 inches).
If warped, replace the rotors.

4. Assess Wheel Alignment and Suspension

Tools Required: Alignment tools or take to a professional service.
Visually inspect the suspension components (control arms, tie rods, bushings) for wear or damage.
If any components are damaged, replace them as needed.
Consider having a professional alignment performed if misalignment is detected.

5. Inspect Tire Condition

Tools Required: Tire pressure gauge, tread depth gauge.
Check tire pressure and inflate to manufacturer specifications.
Inspect tires for uneven wear patterns; replace if necessary and balance the tires if uneven.
