The 21-year-old Brevis, who came into the Chennai squad mid-season as an injury replacement, struck four sixes in his knock as the men in yellow were restricted to 154 all out.
The young South African, who came in at number five, received no real support with the next best contributor Ayush Mhatre who scored 30 while Deepak Hooda made 22 late in the innings.
Brevis' innings was ended 13th over due to a brilliant catch taken on boundary by Sri Lanka international Kamindu Mendis.
Mendis then starred with the bat as he was unbeaten on 32 to guide the Sunrisers to victory with eight balls to spare after they were wobbling at 90-4.
