If so, why is it written [here] "Your brother"?

DEUT1104 If he named the lost object, but not its [Identifying] signs, it should not be returned to him. And if he is [known as] a deceiver, even if he does give its signs, it is not to be returned to him, it being written: "until you seek out your brother" -- until you seek out your brother to determine whether or not he is a deceiver (Bava Metzia 28b)

DEUT1105 [lit. "until seek your brother"] - Now would it enter your mind to give it to him before he seeks it! How, then, is "until seek" to be understood?

By signs i.e., [by giving identifying signs, proving the animal is to be his] -- whence it is derived that [claiming a lost object by means of] signs is a Scriptural ordinance (Bava Metzia 28a)
