When we consider the weight of the sailplane Vs the size of the wheel and brake area, are we expecting more stopping power than is possible? Can we really expect those tiny brakes to do much? Bob Gaines Marietta,

Don't know about others but I can put my LS-3a on its nose on asphalt with the wheel brake.

There's a lot of variables.
Most disk brakes, when in good working order, can easily stop wheel rotation under all conditions, but will that stop the glider adequately? It depends on the traction provided by the runway surface.
My Lark is probably the worst. Stopping a 1300 pound GW glider with a 25mm wide 130mm diameter drum brake is asking a lot. I've just settled for not aiming the monster at anything I want to keep.

On any surface I have to watch the brake I pull, if I don't want to put the nose on the ground. The ASW-24 haves an hidraulic brake plus a large landing wheel that brakes more than enough. Have to be careful with the approach speed though, a little fast than usual and it will roll forever!

Yup, and I skinned the chin of my Nimbus 3 on my first flight because of a very effective wheel brake. Scraping the Gel coat didn't bother me as much as the big bang when the tail hit the ground when the wheel stopped and the nose came back up off the asphalt.
Now I have to modulate the brake until I get the flaps into negative on the roll-out, once the flaps are full negative I can honk on the brake and bring the big glider to screeching halt in a very short distance - tail stays glued to the ground.
Flaps are cool.

Bill, When that Lark was owned by the Albuquerqe Soaring Club I was able to adjust the brake to the point where it worked very well, you could really feel the deceleration, for about 2 landings. After that it went back to its normal worthless behavior.
