A Quick and Dirty Guide to Bleeding Hydraulic Brakes
by Craig Bachler

This guide is designed to help first-timers with the bleeding process. While it's not a terribly difficult job, some of the steps are not always obvious if you haven't done it before. Make sure you don't get brake fluid on any painted surfaces as it will bubble and strip almost anything.

• Fill reservoir with hydraulic fluid.
• Have your banjo fitting at the lever (#1) tight and cracked loose at the caliper (#2). Also have your bleeder (#3)cracked (the small fitting on the caliper near the banjo).
• Wait until fluid starts dripping out of the banjo fitting. Let it drip for a couple minutes, until it's relatively fast and consisitent, being careful not to let your reservoir run dry.
• Once the dripping is consistent, tighten the banjo (leave the bleeder cracked) and then put on and screw down the reservoir's top (making sure it's full of fluid).
• Now you'll need to get into the actual "bleeding" of air out of the line. It's a process of slowly squeezing the brake lever while the bleeeder is open and then closing the bleeder BEFORE letting go of the lever (slowly). **It's very important that you do not let off the lever at all while the bleeder is cracked open or you will suck in air and erase any progress***
• As you do this again and again, you will feel pressure build as you pull the lever. After the pressure builds to your satisfaction, you're done!!

Happy New Year to you all!
