Bench bleeding is a must with new or air contaminated master. I'm sure there are videos if the description above doesn't make sense. And if you think it doesn't matter cause some fluid came thru, It does cause there's still air pockets trapped in the master...usually you can get a kit but it can be made and I have a set in my tool box- cut a short piece of brake line in half so that each one can be threaded into the master and bent to feed back into the res, one for each circuit. Their ends should be below fluid level in the res. Then pump the master via pushrod by hand in a vise on the " bench" or by pedal if it's already installed. Pump steadily and repeatadly a bunch. You see a big glug followed by a bunch of strokes of tiny bubbles. If the tube ends see air during this, start over... it is called bench bleeding because you do it on the bench before putting it in, but a lot of guys just stick it in the oem vise and bench bleed... it's easier to know when your done on the bench however...but you have to bench bleed a dry master...
