Is it acceptable to use two fluid reservoirs on one master cylinder?

Two smaller ones like these, one for the front circuit and one for the rear: http://www.jjcraceandrally.com/race/brake-master-cylinders-accessories/jjc-brake-fluid-reservoir

Then use two sensor caps like these: http://www.carbuildersolutions.com/uk/brake-fluid-reservoir-cap-with-2-pin-plug-and-fly-leads

It would be acceptable, but a very expensive way of doing it. Wouldn't a twin reservoir with a single cap do the same job?

Just thinking of all options before deciding to move or re-do the front lines.

Can't see it being a problem, if linked with a T or Y piece, you shouldnt even need 2 caps. They'll balance themselves out so the level will be the same in both

That cap/switch looks like one from a Ford Ka. I picked one up, along with a short length of the harness at a scrapyard recently for a few quid. It's probably the same switch on most Fords and it is definitely a direct replacement (different plug though) for a Sierra cap - which is what I needed it for as my switch had failed and as it's now part of the MOT.

No problem. In reality it has advantages over a simple single res'; Most tin-top single reservoirs have an internal division that comes 1/2 way up, so that if one circuit bursts, there's still a fluid reserve for the other circuit.

This looks to be what I am after:

The right shape and larger outlets to fit into my master cylinder directly. Anyone know where I can get one in the UK?

I have one that shape but the outlets are too small for the master cylinder seals (and the seals on the reservoir are too small an OD for the master cylinder).

I managed to get one of the reservoirs that I have mounted today, by using some rubber seals from a spare master cylinder.

I have turned it round 180degrees so it now leans back as per the picture below. Is this OK?

If I were an IVA man I would have a problem with that - If not for IVA then I would still not be happy with is from a personal view that it is just wrong and takes very little effort to do right.

Ok, from that I think I am correct in saying that the reservoir in the picture is not usable due to it being designed to mount on a master cylinder with an upward tilt and my master cylinder is mounted horizontal.
So I need to use very little effort and get it right by using a reservoir that is designed to be mounted on a level master cylinder.
