Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on where the pulsation is felt).
Secure with jack stands to ensure safety.

3. Remove Wheels

Use a socket set to remove the lug nuts and take off the wheels to access the brake assembly.

4. Inspect and Replace Brake Rotors

Inspect Rotors: Check for warping or scoring. If warped beyond manufacturer specifications (usually more than 0.002 inches), they need replacement.
Replace Rotors: If necessary, remove the caliper (using a socket set) and unbolt the rotor. Install the new rotor and torque the bolts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

5. Check and Replace Brake Pads

Inspect brake pads for thickness; if they are worn down to 3mm or less, replace them.
Replace Pads: Remove old pads, compress the caliper piston using a brake caliper tool, and install new pads. Ensure they are properly seated.

6. Reassemble

Reattach the caliper and torque the bolts to specifications.
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to ensure even pressure.

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
