Those are 2 separate systems. The brakes can involve vacum. That would come directly from the engine. And steering usually comes from a belt that drives the power steering unit. Did it happen temporarily or is it still doing it ?

If that's the case your PS pump pressure could be bad or you have a relief valve stuck in the system.
