A upright trike nearly always has two brakes, both on the front wheel,
and each pulled by a different lever so as to comply with the "two
independant braking systems" requirement.

Some recumbent trikes which have the two wheels at the front just have
disks/drums on the two front wheels run off one lever and either a
token "parking" brake on the rear (Windchetach) or nothing at all.
Though of course the former is a little dodgy and the latter is strictly
speaking illeagal.
