Have any of you guys experienced the reservoirs on the OE [Nissan] master cylinders busting apart from too high a psi? If yes, what is the pressure limit you found is safe. My pressure bleeder says to use 15 psi, but someone told me 5 psi is sufficient. I tried 5 psi on a non-honda vehicle years ago and as I recall it did not seem to be adequate (rinky dink pressure). The HSM says to use the old fashioned two person system. That does generate the most pressure safely, but I dont have a helper , so . . .

 

I have never been a fan of pressure bleeding. It just seems like a away to introduce air into the system.

I prefer vacuum bleeding. Much simpler and one man operation. Easy to suction any fluid from the MC, then one can remove the reservoir and clean it. Reinstall, refill, vacuum bleed til the cup is filled, dump, refill reservoir, repeat til the fluid is clean and bubble free.

 

From my experience the pressure bleeder is a great way to flush your brake system or introduce brake fluid to the system ( like if you installed new brake master cylinder/calibers/lines, etc...). After you flushed your system I still do the two man method to get out the extra air.

If you change the master cylinder you might pump with with your foot till your blue in the face ( even after bench bleeding ). Change mastery cylinder/bench bleed/pressure bleed/two man.

My co-worker who has been a mechanic from the 60's swears by gravity bleeding. I have never had any luck with that method.
