Bravo, who arrived at the Camp Nou from Real Sociedad this summer, is yet to concede during his first three league games for the Catalan outfit.
The Chilean also revealed his delight with Saturday's 2-0 win over Athletic Bilbao.
"The goalkeeper has to have a zero as his target," Bravo told AS.
"We created a lot of chances and we leave with a good result. We prepared well in pre-season and this victory leaves us very happy."
Fellow new goalkeeper Marc-Andre ter Stegen is still on the sidelines for Barcelona.
