Campaign - Hard Pedal or Increased Pedal Travel: Overview
90olds08

Models/Years: 1986 OLDSMOBILE
CUSTOM CRUISER STATION WAGON
Number: 86-C-15
Date: July 1990

CONDITION
General Motors has determined that certain 1986 Oldsmobile Custom Cruiser 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.
