Solution

1. Preparation

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

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the wheel where the pulsation is occurring.
Place the wheel aside.

4. Inspect and Replace Rotors (if warped)

Inspect Rotors: Use a dial indicator to check rotor runout; if more than 0.002 inches, they may need to be replaced.
Remove Caliper: Unbolt the brake caliper using a socket set, and hang it using a bungee cord to avoid stressing the brake line.
Remove Rotor: Unbolt the rotor from the hub and slide it off.
Install New Rotor: Place the new rotor onto the hub and secure it with bolts, torque to manufacturer specifications (usually around 80-100 ft-lbs).

5. Inspect and Replace Brake Pads

Remove Brake Pads: Slide out the brake pads from the caliper bracket.
Install New Brake Pads: Ensure the new pads are compatible with the rotor type and install them, ensuring proper orientation.

6. Reassemble Brake Components

Reattach Caliper: Position the caliper over the new pads and secure it with bolts, torquing to manufacturer specifications.
Reinstall Wheel: Place the wheel back onto the hub and hand-tighten the lug nuts.

7. Lower Vehicle and Test

Remove jack stands and lower the vehicle.
Tighten the lug nuts in a star pattern to ensure even distribution.
Test the brake system at low speeds to verify the pulsation is resolved.
