SeeEngine CompartmentOverview on page 6‑14for reservoir location andaccess.There are only two reasons why the brake fluid level inthe reservoir might go down:. The brake fluid level goes down because of normalbrake lining wear. When new linings are installed,the fluid level goes back up.. A fluid leak in the brake hydraulic system can alsocause a low fluid level. Have the brake hydraulicsystem fixed, since a leak means that sooner orlater the brakes will not work well.6-33
