Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the battery to ensure safety while working on the braking system.

2. Inspect and Remove Wheels

Use a socket set to remove the lug nuts from the front wheels.
Lift the vehicle with a jack and secure it on jack stands.
Remove the front wheels to access the brake assembly.

3. Check Brake Rotors

Inspect the brake rotors for warping or uneven wear using a dial indicator gauge.
If warped, replace the rotors. If within specifications, clean the rotors with brake cleaner to remove any debris.

4. Inspect Brake Pads

Check the thickness of the brake pads; replace if below the manufacturer's minimum specification.
If pads are unevenly worn, inspect calipers for proper movement and replace if necessary.

5. Reassemble and Test

Reinstall the brake pads and rotors as necessary.
Reattach the wheels and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery and perform a test drive to ensure the pulsating has been resolved.
