Just a quick video teaching people how to use the Parking Brake the right way.
Now if done correctly the car will not roll back, but movement can still be felt. But this is the movement of the weight being transferred is all. When your foot is on the main brakes, it is being held by all 4 tires. But the parking brake only holds the rear tires. So, it is definitely possible to feel the weight being moved from the whole vehicle to just the back tires.
