Replace the brake fluid reservoir and the brake fluid level sensor electrical connector. Do not disconnect the brake fluid level sensor electrical connector, cut the connector 3-4 inches (75-100 mm) from the connector end and leave the brake fluid level sensor electrical connector attached to brake fluid reservoir. Include these parts in the same package when returning warranty replacement brake fluid reservoirs. The brake fluid reservoir with the electrical connector still connected should be packaged in the original box to protect it during shipping.
