What's the advantage of putting in two reservoirs on the cylinders, instead of one reservoir on the firewall?

Maybe I just don't understand the big win here...

I have pedal mounted reservoirs, and like them. They are very easy to check and service. I have a -10, which may have more room and easier access to the footwell than other models. ? I prefer the pedal mounted reservoirs because it eliminates a couple of hoses and connections. Nice and simple.

Paul -it was your description of this method on another thread that swayed me to go this way.... and this: https://youtu.be/bZlq87VXybU

Thanks for the help.

Okay, I'll ask the question:

How do you check fluid level without crawling down there to peek in?

I've got the brake-mounted ones on my Cessna, and it's a real pain. And there are large doors near there, too, to make it easier.

I only find it necessary to check fluid levels once a year, at time of CI. You should be down there anyway lubing up rudder pedal and brake hinge points, checking rudder cable, weldment, etc..... I use a short length of clear tubing, stick it in and put a finger over the top of the tube. I pull the tube up just far enough to gauge the level of fluid, then let it go back into the reservoir.
I take issue with the EAA video. If you fill the reservoir, pedal mounted or FWF, it will overflow a small amount for quite some time. Sticky mess. That mess just drips down the firewall, but obviously it drips on your interior if your pedal mounted.
I fill only 1/2-2/3 full. That allows for expansion.

Six of one..... add this to the never ending debate. I have both types of systems and can't say either is better or worse, just different. The FW mounted reservoir with Vans plastic lines does allow you to see if the resevior has run out. You will see a bubble in the incoming line before it affects your brakes.

Default On the Cessna,

They were a pain --- to check fluid levels, to top off, everything bad. Cannot imagine how I could do it on my RVs.

I have the individual reservoirs on my RV8, had them on the last RV8 also, and they are very easy to service/check with the baggage floor removed as others have said. You can service through the 1/8 vented pipe plug, or just unscrew the cap (thereís an O-ring seal) and the top is wide open. Easy to bleed or add fluid without spilling any. Definitely more difficult on a side by side. If you use the firewall mounted reservoir, I would recommend something other than the plastic compression fittings that come with the kit, because they usually eventually leak. I ended up changing mine on my RV6 to the Safe-Aire push fittings like you use on your plastic pitot static lines. They held up fine and didnít leak - and this is just for the non-pressurized clear plastic feed lines.

750 hours 11 years, per plans from Vanís. No leaks, ever. They will not leak when properly installed. I believe Vanís demo fleet will speak better than I.
However, for some reason, people just donít get how they go together. Safe-air are much more fool proof, not saying anybody is a fool.
