[QUOTE="RiderJoe, post: 1441454, member: 93203"] Just a note about Speed Bleeders: if you opt to replace your stock bleeder valves with them, keep the original valves in a safe, easy-to-find place. I think that Speed Bleeders are very useful if you are doing your own brake fluid flushes without needing a helping hand. And, that is all that most people need to do for routine brake maintenance besides replacing worn out brake pads. However, if brake caliper or master cylinder overhaul, or brake line replacement is needed where a lot of air enters the brake system, then the (original, or direct replacement) free flow valves need to be installed to do your first fluid fill/flush after the repair (unless you can use a vacuum system - MityVac, or similar - that can pull the air out of the system through the bleeder valve). The reason for this is that air is compressible, and it may not be possible to build up enough pressure by pumping the levers/pedal to overcome the spring pressure in the Speed Bleeders. Free air flow is needed to get rid of the large air volume trapped in the brake lines. Once most of the air is out, the Speed Bleeder valves can be reinstalled to help you finish the job. [/QUOTE]
