As the hydraulic fluid in the master cylinder reservoir decreases, the level sensor will detect the loss of fluid and illuminate the instrument panel brake warning lamp. Continued operation of the vehicle with the warning lamp illuminated can result in extended stopping distances.

The master cylinder rear seal, between the hydraulic fluid and the vacuum reservoir, may not seal adequately allowing hydraulic fluid to be drawn into the power assist vacuum reservoir.
Dealers will replace the brake master cylinder on all affected vehicles. Addendum (4-14-97): Vehicles inspected per Chrysler recall no. 707 and found to be outside the listed suspect master cylinder date code range, must now have the master cylinder primary piston replaced (Chrysler recall no. 714).
