how do you bleed brake lines on motorcycles?
There are 2 common methods. Manual bleeding, which is pulling on the lever, opening the bleeder (which has a hose attached and drains into something), when the lever hits the bar closing the bleeder, then releasing the lever. Most professional mechanics who are aiming for doing Quality work (not just Fast work) prefer this method. It's the only method I use and I was the top student in my certification classes. The second method is to use a Mity-Vac. You attach the device to the bleeder nipple, pull a vacuum , then open the bleeder and hold the lever to the bar. You keep the vacuum up and it sucks the fluid out. One step that will speed up Both processes is to suck out the old brake fluid from the master cylinder. I usually just stuff a clean shop towel in to soak up the fluid, and then toss it. You can then refill the master cylinder and proceed with bleeding. Takes less than 5 minutes to do both sides of a dual-disk front end once you do it a time or two.
fill master with fluid open bleed valve on caliper pull lever in half way tie with string gravity will let the fluid flow from the master to the open bleed valve. ( a hose attached to the valve will allow you to collect it) I just catch it in a container throw old fluid keep topping the master cylinder up as it flows through when you get a clear stream at the bleed valve with no air bubbles lock off the bleed valve top up master cylinder untie lever. should now have brakes
