In this tutorial, we learn how to bleed a Shimano break system. First make sure the reservoir is leveled and then take the cover off. Make sure you use mineral oil to clean the top, then rubber band a hose onto the bag. Now take a Shimano spacer and release the fluid by squeezing the lever. When the fluid level has dropped down, fill it back up. When you bleed remember to completely remove the pads, as recommended by Shimano. Replace the pads with the spacer when you are doing this, then you won't get brake fluid on your pads. Remember to always fill the fluid back up when finished, and you're set!
