Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues when working on the braking system.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.
Inspect the brake rotor for signs of warping or scoring. Use a dial indicator to measure rotor runout.
If warped, remove the rotor by unscrewing the caliper bolts and sliding the caliper off.
Replace the rotor with a new one, ensuring it is properly seated.
Reinstall the caliper and torque the bolts to the manufacturer's specifications.

3. Inspect and Replace Brake Pads

Inspect the brake pads for thickness; replace if they are below the minimum thickness recommended by the manufacturer.
Remove the caliper if not already done and slide out the old pads.
Clean the caliper bracket and apply brake grease to the back of the new pads.
Install the new pads, ensuring they are correctly positioned.

4. Check Suspension Components

Inspect control arms, bushings, and tie rods for any visible damage or excessive wear.
Replace any worn or damaged components with new parts, ensuring proper alignment after installation.

5. Tire Inspection and Balancing

Check all tires for uneven wear and replace them if necessary.
Balance the tires using a tire balancing machine to ensure they are properly aligned.
