Just bled my brakes by myself in about 10 minutes. Of course it took me about an hour to source all the bits I needed to make the DIY power brake bleeder kit but it'll be easier next time. Here's what you need to make your own kit assuming you have an air compressor already.
1. An extra reservoir cap (on you can drill a hole in)
2. A tire valve stem
3. A locking air chuck
So drill a hole in the center of the cap just slightly smaller than the "D" diameter shown in the pic.
Insert valve stem into said hole with the valve part facing out. Then remove the valve guts from the stem and the press pin from the air chuck (They didn't open at the 20 psi I had the compressor set to)
Lock the air chuck onto the cap assembly.
Set your compressor reg to around 20 psi and then fill your reservoir up with brake fluid. Tighten cap assembly and you are ready to hook up your air pressure and bleed your brakes without help from anyone. The 20psi does not blow off your reservoir and bleeds the brakes nice and slow.
I thought it worked pretty sweet and saved a bunch of time and effort.
Good luck and be careful. I assume no responsibility for any damage or injury that you may incur while attempting to recreate this.
