I bought a pair of Shimano 105 calipers to replace the previous single-pivot calipers on my old Trek, and have a question. The previous front brake had a dished washer that sat between the caliper and the fork steerer, I guess this was fitted to counter the curved surface of the steerer tube. When I first fitted the caliper I transfer this washer over, but only got about 4 turns of the retaining nut, which I figured was probably not enough. So I removed the washer and got around 8 turns, which I feel a lot happier with, and a test ride using fairly heavy braking showed everything seemed to be in order.
Does anyone know the purpose of this washer, will I run into problems not having it or is the trade-off in a greater thread area worth having?

It is, as you surmised, to make a nicer fit on the front of a curved fork crown.
