    formula partial bleed to remove air

    I just shortened the hoses on some formula brakes and need to remove the air from the lines. THe brakes work ok, but clearly have air in them.

    Can I remove the air with out doing a complete bleed procedure? What I'm trying to avoid is removing the calipers and attaching a syringe at that end? Is it possible to bleed just from the lever end successfully? The brakes have been ridden on for about 25 miles...

    At what end did you cut the lines? If you cut them at the MC end just attach your syringe to the MC port and gently apply suction, if they were cut at the caliper end you will need to do the same thing to the caliper, and then top off the system at the MC.

    Then you should be able to just attach one syringe to the lever end and draw all the air out of the line through gentle suction and then top off the fluid. Tap the lines and Master Cylinder when creating suction, even pump the lever a few times to help dislodge bubbles.
