According to The Formation of the Greek People, by A. Jarde:
The new system took no account of the old politico-religious associations, but created new cults for the new groups; of the four villages of the Marathonian Tetrapolis, three belonged to the tribe Aentis and the fourth to the tribe Pandionis.
Tetrapolis (Attica) on Wikipedia:
Tetrapolis comprised one of the twelve districts into which Attica was divided before the time of Theseus. The district was on a plain in the northeastern part of Attica and contained four cities: Marathon (Μαραθών), Probalinthus (Προβάλινθος), Tricorythus (Τρικόρυθος), and Oenoe (Οἰνόη).
The success of these reforms can be quite surprising, but Athens was just recovering from the rule of the Peisistratids and, after the banishing of Isagoras, Cleisthenes was virtually unopposed.
Thomas R. Martin, An Overview of Classical Greek History from Mycenae to Alexander has a chapter called Persuasion and Cleisthenic Democracy that may interest you.
And, just for the record, the traditional four tribes before Cleisthenes were called Geleontes, Hopletes, Argadeis and Aegicoreis. Glad I asked you in comment before answering this :)
