How to bleed brakes?

How to Bleed Surge Brakes 1 Do not look directly into the reservoir while pumping the push rod as fluid can squirt up and get in your face. Just don't do it. 2 Do not allow brake fluid to contact any painted surface as it will damage the finish. To protect your backing plate assemblies from corroding should you get brake fluid on them, we recommend first spraying them down with a rust-resistant spray before you start this process. 3 Do not reuse brake fluid—it may contain contaminants. Trust me, reusing brake fluid won't save you any money. 4 Never let the reservoir fall below 1/2 full during the bleeding process—air can get sucked in and you will have to start all over.

How to bleed brake fluid without a bleeder?

Method 1: One person will grab the screwdriver again and this time start making long strokes under the master cylinder. This will push brake fluid all the way to the furthest brake. At the same time, the other person will crack open the bleeder valve (only about a ¼ turn, not a full turn) and close it before the other person releases the push rod. t's very important to close the valve before releasing the rod because this will prevent air from getting back into the system. Otherwise, you'll have to start this process all over again and waste a whole lot of time and fluid— not to mention, your neighbor probably won't do any more favors for you. Repeat this process on that same brake until no more bubbles are visible in the container and the fluid runs clear.
