Absolutely not! Unless you are the sole owner of the glider since
new, and unless no one except you has ever maintained it, you have no
idea whether someone else has contaminated the system with the wrong
fluid.

Maintenance manual first, then if the color does not agree, a careful
review of the maintenance logs to see if the system has been
modified. If the color does not match and there is no record of
modification you could be in for a complete brake system overhaul.
