http://www.harborfreight.com/brake-f...der-92924.html This unit works so good when I did a complete brake job and dual master upgrade on my '54 Ford it was over 100+ outside and since I had a few PBR's to quench my thirst I forgot to bench bleed the master,so I hooked it up anyway and within 10 minutes total the system was all bled out and working great.
