1. In an antiskid control system for a multigain hydraulic brake system that includes a multigain antiskid hydraulic valve, an integral-based pressure bias modulation control algorithm for producing an antiskid control current for application to said multigain antiskid hydraulic valve, and a pressure bias modulation high step current that overrides the antiskid control current when the antiskid control current exceeds a pressure bias modulation threshold, the improvement comprising dual pressure bias modulation thresholds, one threshold being active at low wheelspeeds and the other being active at high wheelspeeds.
