Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, brake cleaner, micrometer, and replacement brake pads and rotors if needed.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Remove Wheel

Using a socket set, loosen the lug nuts on the wheel where the brakes are pulsating.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel completely.

3. Inspect Brake Components

Brake Pads: Remove the caliper bolts and slide the caliper off the rotor. Inspect the brake pads for thickness and wear. Replace if they are worn down to the minimum thickness.
Brake Rotors: Remove the rotor. Use a micrometer to measure the thickness. If the rotor is warped (more than 0.002 inches out of spec), it should be resurfaced or replaced.

4. Replace Components

If necessary, install new brake pads and/or rotors:
- For rotors: Install the new rotor and tighten the retaining screws if applicable.
- For pads: Slide the new pads into place in the caliper bracket.

5. Reassemble and Torque

Reattach the brake caliper, ensuring it is aligned correctly.
Tighten caliper bolts to the manufacturer’s specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Remove jack stands and lower the vehicle.
Torque the lug nuts to the manufacturer’s specifications in a crisscross pattern.
