From about mid 94 until 2007, a different actuator is used. It operates at about 1600 psi instead of the nominal 150 psi in the older actuators. Here is a picture of the newer version:

It is a rare occasion when either of these two Auto Park brake actuators needs to be totally replaced. But, both are subject to failure due to leaking seals.
