Coefficient of Friction on Brick Street

I have a case involving a low-speed rear-end collision on a brick street. No information in the NUTI books. The situation was a heavily traveled brick street just outside downtown Dallas, no rain in Texas for months. Hot weather. Lawn sprinklers from an adjacent building have the street wet, but probably not cleared of the oil, dirt, etc. This isn't a serious enough problem to try to close down the street do a test, but I'd like a ballpark figure. I know brick streets get VERY slippery, but the question is HOW slippery? What would be a reasonable coefficient of friction to use in this instance? Hard to find in the literature.... Thanks for any info you might be able to provide!
