[3] At the 1973 European Athletics Indoor Championships gave his best international performance yet with a throw of 20.29 m (66 ft 6+3⁄4 in) which brought him the gold medal ahead of East Germany's Gerd Lochmann and fellow Czech Vlk.

Brabec became only the third Czechoslovak man to win at that competition, following on from 800 m runner Jozef Plachý and triple jumper Petr Nemšovský.

[7] This season proved to be the peak of his career as he achieved a lifetime best mark of 21.04 m (69 ft 1⁄4 in) at the Czechoslovak Championships – this stood as a record until Remigius Machura bettered it in 1982 with his national title win.

[2] He had his highest ever seasonal ranking in 1973, in fourth place behind Americans Al Feuerbach and George Woods and Germany's Briesenick.

Among those he trained were Machura, František Vrbka, Robert Změlík, Vladimíra Racková, Pavel Sedláček, Vladimír Maška and Jan Železný.
