I came across this just surfing and thought I'd share. This is a really cool (to me) diy pressure brake bleeder made out of a valve stem, a common garden sprayer, some hose, and a few other bits and pieces. Best part is you can pressurize it with a little air compressor!

cool hack for sure!

The DIY $20 brake bleeder

 

I've made one like this a while back. Works well. I didn't use the valve stem. I didn't really feel the need for a pressure gauge.

The most difficult part was sourcing a cap for the master cylinder. Parts stores didn't carry the HELP! part number referenced and wanted $30-40 for an OEM cap. I just went to the junkyard and got one for $2. Many European cars use the same cap.

 

Made something similar too but much cheaper, I used a plastic thermos for the container and everything was good until it decided to explode and spray brake fluid all over everything. Now I just connect the line directly to my compressor and take out the whole container, it's annoying to have to fill the reservoir all the time though. The cap I got from a volvo at a junkyard.
