After an unsuccessful 2017 season, Brajkovič rejoined his first professional team Adria Mobil.
In July 2018 the Union Cycliste Internationale (UCI) informed the team about a positive anti-doping test for methylhexanamine recorded by Brajkovič.
Brajkovič could have received a ban of up to two years, but this was reduced to ten months by the UCI.
He initially did not extend his contract beyond the end of 2018.

After his suspension ended in September 2019, he re-signed with Adria Mobil.
His first race was the 2.1-classified CRO Race.
