Shortly after the confluence of Lipa and Mali Pek, the river receives the small stream of Todorov (Cyrillic: Тодоров) from the left, and Železnik (Cyrillic: Желеник) from the right. The Pek continues to the north, curves between the mountains of Homolje and northern Kučaj, next to the villages of Blagojev Kamen and receives the rivers Brodica from the right and Komša and Kisela Voda from the left.
