Request datasheet Support

The Leekr DHB-P is an electrically controlled, fully decoupled hydraulic brake-by-wire system engineered as the "Safety Execution Hub" for autonomous vehicles, unmanned delivery platforms, cleaning robots, and electric towable RVs. Powered by a high-efficiency motor driving a Dual Actuation Plunger (DAP), DHB-P delivers millisecond-level dynamic response and integrates EPB control algorithms to eliminate traditional vacuum boosters.
