RESIDUAL VALVES, for MC below WC.

hay guys, im doin brake lines on a 30 olds im building.
it has all new mid 70's GM brakes, stock GM master cylinder,front disc and a GM 10 bolt with drum.

i deleted the old style proportion valve and went with an aftermarket knob style.
the master cylinder is mounted under the seat.

i have a 2 psi and a 10 psi residual valve so fluid wont leak back into the master.

my question is, does this 2&10 psi residual valve have to be mounted level?
or can it be mounted anywhere?

thanks guys.
B

They don't have to be level, but, mount them close to the master as possible.

Bob is right. Orientation doesn't matter but they should be relatively close to the master cylinder.

As Bob C said: "As close as possible". If 10 inches is as close as possible, then so be it. But if 10 inches is the easiest way, then I say work harder and do it right. This is a voice of experience!!

I dont understand why the res valves have to be mounted as close to the master as posible. The hydrulic presure in the lines will be the same at 10 inches or 10 feet. Can any one explane why they have to be close to th M/C?
Thanks

That is a difficult question for me because I don't have a good answer. When I was in school, I had many questions like: 2 + 2 = 4. Why? " Because that is the way it is". I have read and been told many times by those that are more experienced than I, residual valves need to be installed as close to the master cylinder as possible. The installation instructions that come with all that I have purchased new tell me to install them as close to the master cylinder as possible. I have installed them at the easiest location only to go back and do the job right later and had improved results. These reasons are why I say they should be installed as close to the MC as possible. Yep, 2 + 2 = 4 and that is the way it is.
