[DeTomaso] parking brakes

[Charles McCall]

I confess I don't know if OEM electric parking brake systems work by 
pressurizing the fluid in the line, or if they are a simple mechanical 'arm'
that 
is pulling on a mechanical parking brake?   Does anybody know that for sure?
****Audis use a mechanical parking brake actuated by a solenoid - the second
case. They do not pressurize the fluid in the line. They have some
electronics to ease the brake on if you are moving, but actuating it at any
speed locks up your brakes. They are either on or off.
