Maybe the pedal design is better for its intended use, but not as an e brake. If you had an old style (like on my Regal) you could pull the handle out, and use the brake with varying degree of pressure (it wasn't an on or off deal). And drifting that car up this hill was easy. Take a pair of small vice grips and pull the handle out, clamp grips on the cable, and it wouldn't lock. Take grips off, it functions normally.
Of course, being RWD, with a posi, and real snow tires helped. Before I put the posi in though, I would have to drift the corners with it, but putting the G80 diff in there was like night and day.
Wish I could afford a LSD for the LeSabre.
BTW, if you put your foot on the old style pedal when pulling the handle, and let it come up slowly, it wouldn't smack against the stop. Simple.
Do you guys ever use your parking brakes? I was always taught to apply the brake, then shift into park, so you were never resting on the parking pawl. I've had to rip apart some other peoples cars to fix frozen brakes, simply because they never get used. Which is funny, my dads 2 cars passed NYS inspections, and he never uses the parking brake. Part of the NYS inspection is to test the holding power of the brakes. Which, I guess none of the shops actually do.
My dad was actually one of the people who had to call me at work, when he tried to move the LeSabre, but couldn't figure out how to unlock the brake. The shop that balanced my tires had to come in to the waiting area, drag me out to the car (so the other customers couldn't hear) and sheepishly asks me how to release the parking brake. Ugh. Now, whenever I take it somewhere to be worked on, I usually park on a flat spot and don't use the brake.
