Checking Brake Fluid Level

WARNING: This page is about a different car, the 2007 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

Make sure the fluid level in the reservoir tank is within the standard (between MAX and MIN lines). Refer to "CHECKING BRAKE FLUID LEVEL AND LEAKS ".
Visually check around the reservoir tank for fluid leakage.
If fluid level is excessively low, check brake system for fluid leakage.
Release parking brake lever and see if brake warning lamp goes off. If not, check brake system for fluid leakage.
