In the US, at least, we are often asked by the tower for a braking assessment after landing. Very often I hear that same assessment broadcast by the tower to following aircraft.
I do NOT "rebroadcast" PIREPs. That is not my job, and I have plenty to do on approach and landing. AC 150/5200-30D (pp. 5-15 through 5-20) tells the airport operators how to incorporate PIREP data into their RwyCCs.
The RCAM matrix in AC 150/5200-30D (p. 5-7) shows a very close correlation between the Runway Condition Codes and pilot reported braking action. With allowance for translation from tech-speak to cockpit perceptions, the "Pilot Reported Braking Action" descriptions are very close to what I posted above.
