Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery (negative terminal) for safety.

2. Inspect and Replace Brake Rotors

Tools Needed: Jack and jack stands, lug wrench, torque wrench, brake rotor puller (if necessary), socket set.
Raise the vehicle using the jack and secure it with jack stands.
Remove the wheel using a lug wrench.
Inspect the brake rotors visually for warping or uneven surfaces.
If warped, remove the rotors by unscrewing the caliper bolts and sliding the caliper off.
Replace with new rotors, ensuring they are torqued to manufacturer specifications.

3. Check and Replace Brake Pads

Remove the brake caliper by loosening the caliper bolts.
Inspect brake pads for thickness; replace if worn below the manufacturer's specifications.
Install new brake pads, ensuring they are properly seated and aligned.
Reattach the caliper and torque bolts to specifications.

4. Inspect Suspension Components

Visually inspect control arms, bushings, and struts for any signs of wear or damage.
Replace any worn or damaged components as needed.

5. Wheel Alignment and Balancing

After replacing brake components, take the vehicle to a professional for wheel alignment and balancing to ensure proper handling and wear.
