You can Select Your Vehicle to check if 3W1Z-2005-AA fits your vehicle.

To check the pushrod length, unbolt the master cylinder, place a pushrod gauge against the end of the pushrod, exerting a force of around five pounds, and adjust as needed. After adjustment, reinstall the master cylinder and check for proper brake operation before driving the vehicle in traffic.

To remove the power brake booster unit, detach the master cylinder from the booster, disconnect the manifold vacuum hose, unplug the electrical connector from the brake light switch, and remove the pushrod retaining clip and nylon washer from the brake pedal pin. Remove the nuts attaching the booster to the firewall, detach the booster from the firewall, and lift it out of the engine compartment.
