Royco 782 is the answer. Also 5606 Hydraulic fluid, but the latest Vans Service Instruction is to use the high temp synthetic Royco 782. It is compatible with 5606, but due to the nature of the nosewheel models and that most pilots that I’ve seen who taxi a free caster noose wheel plane tend to abuse and overuse their brakes, you have a risk of a wheel fire if you still use nylon brake hoses and the heat causes the line to slip out of the fitting.
Vans also recommends upgrading the internal caliper O-rings to their Teflon (edit: VITON, not Teflon) versions.
