TO:
ALL CHEVROLET DEALERS
General Motors has determined that certain 1986 Chevrolet Caprice Station Wagons with Powermaster Brake Systems were built with combination
valves and pressure switches which may become faulty. If left uncorrected, these vehicles may experience a "hard brake pedal" or "increased brake pedal
travel". These conditions may be caused by a Cast Iron combination valve allowing air to enter the brake system or by a pressure switch on the
Powermaster Brake Assembly leaking brake fluid.
To prevent either of the above conditions from occurring, vehicles will be inspected and those equipped with the Cast Iron combination valve will
receive a new Brass combination valve. Also, the pressure switch will be inspected and replaced, if necessary.
