Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the battery to prevent accidental deployment of any electrical systems.

2. Inspect and Replace Brake Rotors

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake rotor puller, impact driver.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.
Inspect the brake rotor for warping or uneven wear using a dial indicator.
If warped, remove the rotor by unscrewing the retaining screws and pulling it off the hub.
Install the new rotor by aligning it with the hub and securing it with retaining screws. Torque to manufacturer specifications.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are worn down, replace them.
Remove the caliper by unbolting it from the bracket.
Slide out old brake pads and replace them with new ones, ensuring they’re properly seated.
Reinstall the caliper and torque the bolts to manufacturer specifications.

4. Inspect Suspension Components

Visually inspect control arms, bushings, and struts for wear or damage.
If any components are worn, replace them according to manufacturer specifications.

5. Wheel Alignment and Tire Balancing

Take the vehicle to a professional for a wheel alignment.
Check tire balance and adjust as necessary.
