Simple system that uses the ABS to pump and lock hydraulically either
end or all brakes. Just peachy until some component bleeds down from
age and the brakes let off. I suppose, though, the system would watch
for that with a sensor, and keep the pressure up. Ha, another sensor to
set off the MIL and cost bucks to replace. Of course, park brake (a pox
and a scourge of rust on anyone who calls them 'Emergency Brakes'-just
pull one in an emergency and see what happens) cables seize up from
water/salt intrusion in the cables, so you really can't win...anyway...

My curious mind just wants to know....

I aquired a used 2004 Lincoln LS and it's the first car I've ever owned
where the parking brake wasn't applied "mechanically" through pulling on
a lever pivoted near the floor or pulled out from under the dash or
stepped on with my left foot.

What's the operating system which responds to the finger operated
parking brake switch located on the console and puts on the parking brake?

Is it as foolproof as the older style mechanically operated "emergency
brakes"?

Since automotive technology and complexity has advanced to a point where
I find myself "fixing my cars with my checkbook" more often than with my
own tools, I haven't bothered to aquire a shop manual for this beast
yet, and may never, so I can't look there.

Thanks guys,

Jeff
