Narrative:

During landing at vsf; the aircraft became unable to stop using normal braking. After ground flaps were selected; the pilot flying said that the aircraft was not slowing down. With approximately 2;000 ft remaining on the runway; I glanced at the pfd and saw 85 KTS and yelled for the pilot flying (type rated pic qualified and sitting left seat) to apply the emergency brake. Upon application; the aircraft slowed and once the rudder lost effectiveness; the aircraft began to lose directional control. The aircraft spun 1/4 [turn] clockwise and came to a stop with approximately 150 ft of runway remaining. After our arrival on the ramp; we exited the aircraft to find the entire surface covered in solid ice. After discussing the night's weather with the locals; we determined that it was; in fact; freezing rain (unforecast) which coated the runway and made normal braking ineffective. A condition report would have lead us to divert to one of our selected alternates; but as the FBO had already closed; no one was able to make a report and we encountered the conditions unexpectedly.

Title: C525 Captain reports reduced braking capability after landing at VSF. The aircraft is stopped just prior to the end of the runway using emergency braking. The airfield was found to be coated with ice by freezing rain which was unforecast and unreported.
