Ans 2 - get a manual and MAKE SURE the springs and ratchet mechanism is in good shape ! The springs can break, the ratchet can separate from the spring etc.

Take off the brake caliper, and brake rotor, under the rotor is a parking brake shoe, that is probably wore down and needs replaces. I
You would have to find a tube or something to release the handle and ratchet.
First, push the clutch/brake pedal all the way in (forward) with your left foot. Then, while holding that pedal in, lift the small handle (the parking brake) on the right side of the engine housing (just above the right foot rest area) with your right hand. While holding the small handle all the way up, release the clutch/brake pedal. The pedal will move back only a short distance and stay there. The parking brake is set. To release the parking brake, just push the clutch/brake pedal forward and the small parking brake handle will fall down, releasing the parking brake. By PhilfromPA
Start by looking over the mechanism for the Pacifica parking brake. Make sure that the parts operate freely and the ratchet is working. If the unit is not simply stuck, then it will have to be replaced as a whole assembly.
