ACDelco announced its new Professional DuraStop remanufactured power brake boosters are now available. The company said the initial offering includes 234 part numbers (188 GM and 46 non-GM). A second offering of 80 part numbers is expected to follow later in the year. The brake boosters are leak tested and feature 100% new seals and O-rings. All cast-iron units are coated to help extend part life and prevent corrosion, and dust boots, diaphragms and check valves are inspected and replaced if required. The boosters have a 12-month, 12,000-mile warranty on parts.
