The primary job of the Judicial Branch is to interpret laws and uphold the US Constitution. The most common activities are resolving disputes and trying cases that arise under federal law.
The Judicial Branch also performs an important function in the federal government's system of checks and balances by using judicial review to ensure laws, executive orders, policies and treaties relevant to cases before the courts are constitutional.
Assessing the most important job is really subject to interpretation.
Perhaps the most important and primal duty of a court, its first reason for existence and ultimate moral responsibility, is to judge guilt and pass sentence on criminals. Note that it is not the role of the court to judge innocence, they never find a man innocent, only "not guilty".
In addition commerce would be impossible without the courts as a neutral arbiter of contracts and judge of financial responsibility for both injuries to people and losses of property.
Courts also play an important role in deciding the proper legal owners of property and the providence of real estate and chattel. Especially in the probate courts that deal with the disposition of a person's goods after their death if they don't have a good, valid will.
Beyond that the power of the appellate courts to interpret and pass judgement on the constitutionality of laws is vital in preserving liberty and protecting the citizenry from the excesses of government or sudden swings in public opinion against a minority that could otherwise be rapidly stripped of rights.

The Judicial Branch's main power is to interpret laws.
The judicial branch has checks on it because the judicial branch does not create laws in the USA, the legislative branch does. The judicial branch's job is to interpret and apply laws in a just manner. The judicial branch balances the other branches because the judicial branch decides whether the laws enacted by the legislative branch are legal (not against the Constitution) and whether the laws are followed legally by the executive branch and the legislative branch.
