Parking Brake Valve Mount Location?
 

I know I've stumbled across photos on the web at various points, but you can never seem to find them when you need them. This seems to be a relevant topic for the archive, so I am posting this request.

Where or how have others been mounting their brake valves on the side-by-side RVs? I am particularily interested in the 7A, but I think it is probably similar on all models. I am guessing that the easiest method would be to remove that bracket that I previously riveted and just use the valve as the transition point, but I am curious what others have done.

Any links or pictures?

Thanks,

That's exactly what I did. I removed the existing bracket and fashioned another for the same location. I'm planning on using the tab at the top for an adle clamp to hold the cable housing in place.

Here's where I installed it on mine:

I have not done this yet, but I plan to install the valve in the brake lines on the floor in front of the fuel valve. I will modify the floor cover so it covers the valve with just the lever (or an extension on the lever) sticking out. The lever will need some type of lock so it can not be unintentionally moved. The plan is that I will reach down, unlock and move the lever then push on the brakes. This location should be easier to install than on the firewall and would save on the weight of the bracket and cable. I know others have thought of this floor location, so any comments or photos would be appreciated.

Here is what I did:


Here is the cable routing:


Note, this is a tail dragger so the valve had to be mounted higher than on an "A". However, I really like the way Dave made his support bracket.

Caution.
 

Looking at the pictures on this thread, I wonder whether some have not noticed the actual throw through which the lever needs to be moved to take the valve from open to close is 90? and if mounted upright cannot be pulled closed from above.

I have mounted mine in similar fashion to a lot of pics here, but I ground the lever off the shaft, ROTATE IT 45 DEGREES, and weld it back on to the shaft.

Make sure you remove the sahft from the valve first or the O rings won't work well after welding.
I have a Taildragger so mine is on the firewall, but the above applies.

I used Dave Parson's method and am very happy with it. It doesn't require any modifications to the lines. Need some new fittings is all.

Adel clamp needed an extra bracket my way, I wish I had done it like Dave!

Sorry, but I am WRONG
 

I have just been contacted by a good mate, who rather than make a posting, has told me privately that I am wrong.
He is correct.

What I said about repostioning the lever on the Park Brake was ONLY necessary on my RV-7 because I mounted the park brake HORIZONTALLY on the firewall as the brake lines need to penetrate the firewall on a taildragger and it offered a solid mounting.

It does not apply to Nose Draggers if you mount it vertically.

He also drew my attention to a drawing from the manufacturer that I had not seen which is copied below.

So disregard everything I said after "Hello".

Floor Mounted Valve
 

I have not seen any examples of the valve on the floor so here is my attempt for those interested. The lever is held in the OFF (aft) position by the spring. If accidentally kicked towards the ON position it will spring back to OFF. To lock it ON the hinge pin is moved across the lever. The eyelet in the hinge under the cover is squeezed to give a tighter sliding fit on the pin. I may also install a similar hinge pin to lock it in the OFF position as an extra safety measure.
Some tips if you are considering doing something similar.
I made my cover from fibreglass. It is attached to the aluminium floor cover. I think it would be easier making it from aluminium.
Make the cover as low as possible. The higher it is, the longer you will have to make the lever and the slot.
The cover is correctly positioned when the lever in the vertical position is in the middle of the slot. The slot has to be fairly long.
I did not understand how this valve works when I first started thinking about installing it. So in case there are others as thick as me, the lever is not like a hand brake on a car. When the lever is in the ON position it is simply a one-way valve. You can either put the lever ON and then press on the brakes or press and hold on the brakes and then put the lever on.
