When they put it on mine, it made the dolly noticeably heavier. The older brakes had a tendency to flip over, especially if your tires were low. I guess I like the new ones, I use them all the time because of the levers are easier to grab. They don't brake as well as the old ones, but better for me because I never used the old ones anyway. I had to have them trim the levers back a few inches because they would hit my thighs when I went down the ramp. It's my understanding that they no longer make the old ones, so they can't get parts for them. If you want them, break yours, they will be forced to upgrade. The only other thing is it gets in the way of the baggy on back, so if I put a 1 gal split in it, it leans against the cables and makes the brakes rub a little. I used to put film wrap in the baggy, but can't anymore.
