He is bleeding a hydraulic master cylinder for a slave cylinder for his hydraulic clutch, not car brakes. I do not disagree with what your saying for car brakes.



My reference was and is to a clutch master and slave, not brakes. It all depends on what system you're working on and especially the bleeder screw diameter and side port sizes. I had a 1/8 NPT bleeder on my Wilwood slave and besides the extremely short tip that the bleeder hose didn't want to stay on, the port diameters were so tiny I couldn't overcome the resistance force with the oil can I have. Hence my earlier comment. I removed the bleeder screw and bleeder screw adapter and machined the adapter for a larger 5/16 NPT bleeder with larger ports. Resistance dropped and ease of bleeding went up dramatically. I also ended up with a larger head on the bleeder screw for better fit with the bleeder hose.
