Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Brake Components

a. Brake Pad Inspection

Remove the wheel using a socket set.
Inspect brake pads for thickness and uneven wear. Replace if below manufacturer specifications (generally 3mm or less).

b. Rotor Inspection

Measure rotor thickness using a micrometer; replace if below minimum thickness (typically stamped on the rotor).
Use a dial indicator to check for rotor runout. Replace warped rotors.

3. Wheel Alignment Check

If the inspection shows misalignment, take the vehicle to a professional alignment shop.
Ensure the alignment is adjusted according to manufacturer specifications.

4. Tire Inspection

Check for uneven tire wear patterns; replace tires if necessary.
Balance tires if required to prevent vibrations.
