1, what is a rrc ? 2, who gave you the number and do they know what they are on about ? 3, have you googled and asked a specialist , there are a lot of people dealing with ex military vehicles and they will know what you need and what number it is , as google does not show anything .

Rrc- Range Rover Classic Number given to me by dunsfold Land Rover, who are the leading authority after Land Rover themselves, and hold a number of pre-production models in their collection I did try google first @waxoyling Lyrical - thanks dodgerover -I’ve had problems with paddocks before, and now refuse to use them

Just struggling to understand that aspect .

Colin You’d be right Colin, it’s a specific part as fitted to the six wheel variants, and it’s not supposed to be replaced with the standard item

If you give us as much information of the old part I will do some digging, a mate of mine is a specialist brake parts supplier so I may be able to pick his brains
Try and get the makers name which could be on the reservoir, any ID tag numbers, casting number and hopefully the bore size will be cast into the cylinder as well, a few pictures might help

For a while I’ve not been happy with the amount of pedal travel on mine, although it stops ok, so I started researching it It also doesnt help that there are several variations of the standard cylinder, including thread types and so on, Land Rover do like to make things complicated!

A bit more digging has come up with a Carmichael number of CO5/220 which means not a great deal on s search

I will try to help.....(My wife will!). My wife works for the MoD and used to work for RAF MT supply and would have used these numbers which I shall explain. The number: 2530-99-825-6389 is not a part number. This is a NATO stock number, (NSN). The number is broken down into three sections. The first 2530 is a group category so could be such as an example gaskets or electrical or what appears to be a generic mechanical part. The second number is specifically for each country of origin relating to NATO that codes the parts. In this case this is UK which is a good start! The third number, even if it’s broken into two sections is the last seven of a 13 NATO number. This number is allocated by the MoD for a specific part that is manufactured by a company that has set up a contract with the MoD. If the part is remanufactured by another company with an MoD contract and the item has not been changed or modified the number will remain the same. If it is modified then the number will change. With me so far? As the number is MoD specific you will find this next to impossible to establish what this number relates to exactly. If you are part of a club relating to these vehicles you may find that they may have a microfiche with parts for this vehicle that can be cross referenced. If you need help though my wife will have a look on the MoD system for you and see if this NSN will come up with something for you?

My wife has checked the NSN and it is confirmed that the number relates to “Master cylinder assembly” Made by Carmichael with their part number C05-220. I can see you already had this information. Carmichael’s address is/was Weir Lane Worcester WR2 4AY 01905 420044 It appears they are now known as: SIG www.simonigl.comHope this helps as it appears Carmichael still exist in some shape? What is the vehicle anyway as it appears this wasn’t a Fire tender or was it converted back for civilian use?

That’s one of the issues, there were quite a few companies in the business of manufacturing them back in the 80s when this was built, but they all went bust I have seen one with an electric sunroof and hydraulic seat so you could go falconing in the desert, strangely mine doesn’t do that!🤔 Thanks again for your help

I’m just thinking are you 100% that your vehicle was manufactured/converted by Carmichael?
I see you refer to Dunsfold quoting you the NATO number however firstly if your vehicle is a Carmichael then clearly it’s not a TACR fire tender and I’m guessing therefore would not be an MoD variant and in which case would not have NATO NSN reference numbers anyway.
Secondly looking at the images (I see you removed a couple) I’m confident that this is not a reconverted fire tender back to a Range Rover looking at the bodywork and as such would be an original conversion, which then points back to by whom?
Why did Dunsfold give you this number? Did you describe to them that you had a 6 wheel version and they assumed it was a TACR?
I’m just curious now!

I read it that JNR converted classic to 6 wheels Brakes are rubbish, spoke to dunsford to see what was fitted to their 6 wheelers, was given a NATO part number for the part fitted to their vehicles, but everyone has stopped trading and even with new info still drawing a blank. Would this be a triple circuit system, or just a double that shifts more fluid (sorry, you probably don’t know that )

No I don’t think it’s a Carmichael, I only think it’s a JNR because of the other vehicles converted by them look the same, there’s a huge amount of variation between manufacturers in the design of the rear wing/window/roof area, my rear wings are fibreglass and the window was one piece glass with a trim down the centre before it broke, my roof is two (1 3/4) rrc roofs with a custom mage reinforcement section underneath I told DLS I believe it be be a JNR and that’s what they came back with. I am as sure as I can be that it was built pretty much the way it is now, although since 1983, who knows? It’s certainly had loads of modifications in my ownership in the last 13 odd years
