Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Safely jack up the vehicle and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the wheel is still on the ground.
Lift the vehicle and remove the lug nuts completely.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Use a micrometer to measure the rotor thickness. If below minimum specification, replace the rotors.
If rotors are warped, use a rotor resurfacing tool to smooth the surface or replace them.
Install new rotors, ensuring they are properly seated on the hub. Torque the rotor bolts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Examine the brake pads for uneven wear; replace if necessary.
Clean the caliper bracket and apply anti-squeal lubricant to the back of the new pads.
Install new brake pads into the caliper bracket.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications (typically around 100-120 ft-lbs).
Test drive the vehicle to ensure the pulsating issue has been resolved.
