We only have rear brakes. Normally we use them very little, usually below 200 and at turn out. However one time in 26 years, we lost all our chutes. I was at the 5 and 1/2 when I realized NO CHUTES. Finally got stopped at about the 7 and 1/2. It was nice that we did have brakes, even though you can't use them very hard. Not enough traction from the tires to really make use of massive brakes. But you do need enough that they won't burn up at speed.
