Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery (if required for safety).

2. Inspect and Replace Brake Components

A. Check and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake rotor removal tool (if necessary).
Remove the wheel to access the brake assembly.
Measure the thickness of the rotor using a micrometer; if below the minimum specification, replace the rotor.
If warped, replace the rotor with a new one, ensuring to clean the hub surface before installation.
Torque the rotor to the manufacturer’s specifications.

B. Inspect and Replace Brake Pads

Remove the caliper by loosening the caliper bolts with a socket set.
Check the brake pads for thickness; replace if worn down or uneven.
Clean the caliper bracket and install new brake pads, ensuring they are properly seated.
Reattach the caliper and torque the bolts to the manufacturer’s specifications.

3. Wheel Alignment and Balancing

If the brake components are in good condition, proceed to check the wheel alignment.
Use a professional alignment machine to ensure that the wheels are properly aligned according to manufacturer specifications.
Balance the wheels if any imbalance is detected.
