pressure will be the same from side to side on the front or rear regardless of length. Pressure is not affected by the distance of the line, or difference in length of lines.
distance does not change the volume of fluid required to transfer kinetic energy either, it only requires a larger volume of fluid to fill it.
Loops are for absorbing the vibration and giving the hard metal line enough room to flex without breaking, it has nothing to do with brake balance or cooling.
The loops in the picture are rendered less effective as the are fastened down next to the master on the firewall, there is no flexing going on here, but the technician who posted it was absolutley correct in what he said. Also he does really nice work as is evident by the photos.

But by making the line longer on one side the distance is now the same . Or balanced . Get it ? If it was just for body flex they could use rubber . Think about it if you kept flexing that line it would fatigue and brake . Dose the fluid get a benefit of cooling well yes .
And that is almost as funny.
And by the way, I can see why someone would believe such a thing (making them equal length) but after reading the thread if you STILL believe that, I just don't know what to say.

That was Mikey out of Gilroy California. I had the good pleasure of stopping by his shop once, he is a SUPER talented guy with three brains worth of information and knowledge to do with building cars. I sure miss seeing him here. He got a job with an up and coming Electric car company in their R&D department and he keeps so busy there he has no time for the little people.

you are all wrong

This was Fords idea for the assmbly line in detroit to support the master cylinder for the next guy to add his parts. I know because my son in law worked for Ford

It may have accomplished that, but the coils are for vibration control.

no
it's for the loop de loop.
it is a well known fact among the scientifical community that brake fluid digs loop de loops.

I don't need to be right but...

I'm not sure but I was told by my dad , it added "feel" to the pedal ,or more touch control to power assisted units, to prevent lock ups. Which is unnecessary with today's anti lock brake systems. and I don't see them anymore for some reason .

Original designed

like a coil spring to support the Master cylinder for the next guy in the assembly line this was done in late 1960s by Ford if vibration is limited all well and good but that was not the principle reason for the coils I worked in a ford garage back then and I know what it was for from my son in law and Ford reps

Well I am confused as hell here. The lines would go on the master cyl last so just what would they be for? I am trying to wrap my head around this and I can't but it's been a long day.

Under what circumstances would you put the lines on the master cyl before the master cyl was bolted to the booster or firewall? I have never worked on an assembly line but I just can't grasp this. If the master cyl went on first then the lines there would be no reason for these coils to "support" anything and if the lines were in first and then the master cyl was installed, again no reason to "support" anything, explain to this old guy would you please?

In a word nope, sorry, no cigar. But my dad told me to "pump" the bat before you swung at the ball. Bless his heart RIP.

I buy that reasoning and experience always trumps, "I Heard" any day of the week!
