Brake line size?

[craigerdesigns]

okay

Craiger, not exactly sure I understand you responce to me? I dont think anything in my post implied I was try to work outside pascal's law? I was basically listing info we learned in basic hydraulics. You can put 5" hard lines but you will still have the restiction at the connections at master and slave. These holes will usually be smaller than any line in system I am sure. These holes will act like an orfice tube in the system and limit/slow speed or flow but will still not limit final pessure. Have you ever looked at the size of hard lines on auto lifts? We have a older challenger and the hard line from the pump is aprox 3/8" ID and that feeds both cylinders to lift 8000 lbs. Aslo one note if ever want to know which line is suction and which is pressure to cylinders? The small line will most always be the high pressure line runnnig 2000lbs.

Anyway before anyone starts fitting 1" brake lines made from black pipe to there car go to youtube and search pascals law or hydraulic principals i am sure you find alot of good info. Like I said if you think a AN-4 line will lower pressure look into the outlet port of the master at the size of the hole. Anyway i'm done here and going back to what we do every night TRY TO TAKE OVER THE WORLD!!!! dont listen to me google it!

I wasn't thinking about the orfice, but in my stock master cylinder application with 3/16 lines I run a bushing on the master to reduce to my 3/16 line. What I am focusing on is that a 3/8 line is less resistant to flow than a 3/16 line. I know there are other factors but if everything else is the same it will take less force to move the same amount of fluid through a bigger line than a smaller line. The only way to know for sure is to set up a real world test, which is what one guy on here said he did. According to him it did make less pressure with the bigger line.
