Here's a quick tip video on hydraulic brake maintenance.

Over time air can build up in a hydraulic brake system, or there might have been some trapped air that wasn't removed from the last full brake fluid replacement. Ideally this can be quickly checked every 50 hours or so, but at most you should check it around every hundred hours, especially if you put a ton of hours on your bike.

This also depends on the type of riding you do. If your constantly hammering your brakes on downhills then you'll want to check them more often than if your mainly riding xc trails

This is a quick job, in all it should take less than 10 minutes and is well worth the time.

Hope this helps some folks out there
