Question on dual master brake setups
Hey guys, when you are testing for brake fluid leaks, what is the highest PSI you test for leaks?
I haven't got the system fully bled yet, and I spotted two leaks at 550 psi in the front which I have to tighten even more. It won't leak below the 550 mark. The rear never leaked at it's highest point of 400 psi.
I know I won't have the car running those levels however I want to have a leak free system are there any guide lines.
if I remember correctly it's a 3/4 and 7/8 master cylinders....
Thanks for any help!

Well if you work backwards through the system you can figure out how much YOU can put through them.
A really hard pedal can be around 120 pounds of pressure at the pedal a soft one can be down around 80. Multiply that times the leverage of the pedal itself, probably around 6:1 and you get 480 to 720 lbs at the back of the master in hard braking. Your 3/4" master has .44 sq inches so you will end up with 1090 to 1635 PSI in the lines.

What type of plumbing are you using? If you have AN plumbing, and you have a leak that is being difficult, then put a copper cone shaped seal washer in the leaky joint.
Brake pressures can go over 2000 psi.
