Brake Fluid Has A Shelf Life On The Bike

Brake fluid is one of those maintenance items riders forget because the reservoir still has liquid in it. That is not the whole story. Brake fluid absorbs moisture over time, and old fluid can affect performance, feel, and boiling point.

Check the service schedule. Look at the colour. Notice lever feel. If you do not know when it was last changed, that is useful information by itself. Fresh fluid is not glamorous, but good braking rarely is.

You do not have to do every job yourself, especially if brakes make you nervous. You do have to respect the job enough to get it done properly.
