Tricolorul Breaza

Football in Breaza appeared after the First World War, with the press of that time recounting the story of a match played in 1924 in the commune from Prahova Valley between Tricolorul I from Breaza de Sus and Principesa Ileana I from Câmpina. The team was not registered in official competitions, playing only friendly or demonstration matches until 1941, when it was disbanded due to World War II.

In 1951, the club was re-established as Tricolorul Breaza de Sus and was registered in the Câmpina District Championship. In 1953, its name was changed to Recolta Breaza after the two communes, Breaza de Sus and Breaza de Jos, united to form the city of Breaza. It changed its name to Steaua Roșie in 1957 and was disbanded in 1966.

The club was re-established in 1971 as Tricolorul Breaza and entered the Câmpina Territorial Championship, which it won, earning promotion to the Prahova County Championship after a play-off tournament. Until 1991, it played exclusively at the fourth division level, where it finished 2nd twice, in the 1974–75 and 1976–77 seasons, and changed its name to Precizia in 1983.

After the 1990–91 season, due to changes in the competition system by the FRF, Precizia Breaza was forced to play in the fifth division the following season, even though it had not finished in a relegation position. It secured promotion after one season by finishing in 2nd place. This was followed by nine seasons in the fourth division, during which the club changed its name in 1993 to Hidrojet, after the name of the factory that sponsored the club.

Hidrojet promoted to Liga III at the end of the 2000–01 season, winning the Liga IV – Prahova County and the promotion play-off played against Aromet Poșta Câlnau, the winner of Liga IV – Buzău County 2–0 at Tractorul Stadium in Brașov.
