I think the Deore brakes are single piston. Both mine and wife's MTBs are using it. The only double piston brake calipers by Shimano is the Saint which are mainly used in downhill bikes. Double pistons means 4 pistons, two on each side. Once you take out the brake pads, you can see more clearly. Double pistons works such a way the the 2 smaller pistons will touch the rotors first before the 2 main pistons clamps in for better modulation.
How's the folding of the brake hydraulic hose? Better be cautious when you fold as the hose don't bend as much as the conventional cable type housing. Happy riding with your new possession. The Dahon Dash is a fine workhorse.
Thanks for your explanation on the hydraulic brake. I thought when two caliper moves, it's called twin piston. As for java fit, only one side of the caliper moves.

I've pay attention to the way the hydraulic cables fold, it looks OK. Hopefully it can last.
The rd cable is the one worry me, it pull long after fold and when unfold, the cable doesn't go back in place, have to push it back in position.
I've see the new dahon dash routing for the rd cable goes thru top tube instead of bottom tube. Maybe they realise the problem.
