Motorcycle brake fluid change

Because brake fluid absorbs moisture over time, it needs to be changed in order to ensure that it retains its properties and to prevent mechanical parts from wearing out.
Draining out brake fluid is a risky operation if not carried out properly – air bubbles can get into the circuit. Be careful – brake fluid is highly corrosive. It is therefore a good idea to protect the various components which may come into contact with it.

The manufacturer's service manual will tell you how often you should check the level, and how frequently it should be replaced. As a general rule, the brake fluid level should be checked every 100 km or every month or so, and it should be changed around every two years.
