Reply to "Brake Bleeding"

I had some people ask me about this so I will elaborate on some things.

The pump is a vacuum pump. It was originally used for medical but appears to be a Badger air compressor with the ports reversed. It pulls 25" of vacuum. There are several pumps available through ebay and different sources. It is key that it can pull at least 20" of vacuum but it does not need much volume.

The vacuum pump is just hooked to a tank to catch the fluids so they do not go through the pump. I made sure the top hose is clear so I can watch for bubbles. the black hoses are sized for the bleed ports.

One problem I had with vacuum bleeding was air getting around the threads so I make sure there is thread sealant on the threads AND I put thread sealant around the base of the bleeder. This works well to prevent air from coming through the threads.

With both bleeders on the Wilwood calipers hooked up you can really go through some fluid so make sure you keep the reservoir topped off. This is good for getting difficult air bubbles out as you can really pull some volume.

I like to tap on the calipers as it flows to release bubbles stuck on the caliper wall.
