Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Remove the lug nuts with a socket wrench.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor without damaging the brake line.
Inspect the brake pads for wear; replace if they show signs of uneven wear or are below the minimum thickness.
Install new brake pads, ensuring they are oriented correctly.

4. Check and Resurface/Replace Rotors

Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Measure rotor thickness and check for warping. If warped beyond specifications (usually more than 0.002 inches), resurface or replace the rotor.
If resurfacing, ensure it is done to the manufacturer's specifications.

5. Reassemble Components

Reinstall the rotor onto the hub.
Reattach the caliper and tighten the caliper bolts to the manufacturer’s torque specifications (typically around 25-30 ft-lbs, check for exact value).
Reinstall the wheel and tighten the lug nuts in a star pattern.

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper pressure is restored.
Test drive the vehicle to confirm the pulsation is resolved.
