Checking Brake Fluid
Check brake fluid by looking at the brake fluid reservoir. See Engine Compartment Overview on page 10‑6.

The fluid level should be above MIN. If it is not, have the brake hydraulic system checked to see if there is a leak.
After work is done on the brake hydraulic system, make sure the level is above the MIN but not over the MAX mark.
