An improved hydraulic brake booster including a booster cylinder and a dual-circuit main cylinder connected together. The brake booster includes a booster piston which defines a storage pressure chamber and the dual-circuit main cylinder includes a double piston which defines a primary pressure chamber. A separating wall is provided which is connected to both the booster cylinder and the dual-circuit main cylinder and separates the storage pressure chamber from the primary pressure chamber. |
