Dual Brakes

RV7AJeremy · #1 04-09-2013, 08:25 AM

I am trying to wrap my head around how this system works/if it will work.

I am installing dual breaks; I intend on using one grove brake reservoir on each master cylinder on the co-pilots side, then the rest of the system to the plans. I like the idea of the separate reservoirs to simplify the system and eliminate one firewall penetration. What I can not figure out is if the brake lines are routed from the copilots side to the pilots side go higher than the reservoirs, wont gravity force the fluid back out the top? The only thing I can think of is that the ?breather valve? on the top is porous enough for air, but not for the break fluid? Can someone help me out with this? Maybe I am displaying my stupidity here, or maybe my intended design will not work. Thanks for the help.

Hi Jeremy, I would recommend going the single reservoir route only because it is a real PITA to go under the panel with a light each time you want to check the fluid or bleed the brakes. It can be messy as well. Just food for thought. Larry

Jeremy,

I was going to switch to individual reservoirs when I added the brakes on the passenger side. When I did the install, it was so easy to just hook to the existing reservoir, I just did it like the plans. I haven't done a pressure test, but it all went together pretty easy.

I think you guys are probably right.....what I can get over is how cheep the vans supplied reservoir looks. IMHO, it doesn't look like it belongs on an airplane.....does anyone have any suggestions of a firewall mounted alternate reservoir?

Thanks all

I remember someone posting links to some pretty nice reservoirs - some polished and some anodized. They looked pretty nice, but were pretty expensive. Maybe just paint the stock one?

I will see if I can find the links.

Jeremy you can go with more expensive one

Vlad I have that one from Blue sky aviation and I love it. Check the fluid via oil door. It is really easy and works great.

Here is the one I installed. Not cheap at around $80, but not a bank breaker either:

This is the one I looked at. It looks sharp and well made.

Hey Carl I am wondering if I can retrofit similar ones on master cylinders instead of metal. Long time ago I emailed Noel asking about this possibility but never heard back. Do you have a closer picture of the top and bottom? How thick is the polymer?
