    At least two of the own 101s so I think that should be fine.
    It's not Martin, is it?
    Able Engineering?

    Oh, and I see it's your first post, Howard.
    Welcome to the forum.
    I look forward to more posts from you keeping us updated as to what is happening in the 101 world in the UK.

    (I don't know how strict your moderator is on mentioning companies names but I know this company send parcels of 101 spares to Australia quite frequently so some of your members may know of them.)
    This conversion uses standard Landrover calipers and fit inside standard 16" steel rim, the radio body with the red 'jerry cans' is on 17" alloys and the light grey is on 16" alloys, the discs are 15 thk and machined in the correct grade of cast iron for brake discs, the double ended wheel studs are made in a heat treated nickel chromium molybdenum steel lengthened by 10mm to the suit alloy wheels.
    Using the wheel stud back face on the hub as a mounting face for the spacer ring has it's problems, they look machined and you would assume that they are flat and level with each other, but they aren't, it took us a couple of attempts to machine these faces in a lathe to get the spacer ring running true, we found the best way was to use a spare stub shaft and bearings as a mandrel in a lathe, to mount the hub on, DTI checking as we went and then machined these faces flat to get a true running face for the spacer ring.
    The conversions haven't improved the braking effect much, but they help to prevent brake fade and pull up square under hard braking, the radio body with the red 'jerry cans' towing a trailer can exceed 5 tons gross. Aftermarket brake pads such as EBC's are being trialled.
    The existing 101 servo is 8" dia fitting a 9" servo would increase the servo assistance by 25+% this is something to be looked at.
    Also looking at a power steering ram/electric pump set up similar to the Haystee but cheaper !!
    Tried not to ramble too much, thanks for reading if you got this far !!
    Cheers

    Welcome to the forum.

    The original master cylinder and booster aren't designed for disk brakes which usually require more force to make them work properly, so without changing these as well, you'll still need a strong leg. A D1 dual diaphragm brake booster is an easy fit and makes a HUGE difference to brake pedal pressure even with the drum brakes. It's the single biggest improvement I made to mine. I can lock the front wheels up if needed with the drums now, but as you say, the disks are far better at making it pull up straight and consistently. Disks are my next investment on mine I think.

    There is a guy over here that is developing a disk brake conversion for the 101 but it's still a ways off by the sounds of it - I'm happy to wait though.

    Oh and feel free to post some more details of your 101 - maybe start a thread on it here. . Maybe even tell us a bit about the jeep in the background too.
    If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.

    Welcome to the forum.

    The grey 101 is Martin (Able) Howdle's own - 4.6 rover and the other is his friend Steve Taylor's - 4.8 rover. (they can both be found on facebook)
    They found !! 2 brand new front and rear axles somewhere and used them in this conversion.
    Allegedly retired, I do the drawing work for Able and other local small companies who can't afford a full time person
    Did this design before seeing your long running thread or seeing the Zeus details
    the disc is 340 diax15 thk inside a 16" steel rim
    Another hobby of Martin is producing parts for a Lancaster bomber rebuild - to get a 2nd one into the air in the UK - guess who has the job of redrawing some of the 22,000 jpg drgs
    The willys jeep is another of Martin's toys !!
    Cheers

    Disc Brake Conversion Comments

    Thanks Homestar, for the 'heads up' about the D1 Servo, this has really made the conversion worthwhile, any disc brake conversion needs 1 of these servo's fitted,
    both 101's mentioned previously have now done significant mileage and some heavy emergency stops (on purpose)(in a straight line) without any problems !!
    below is a site showing more of the disc brake conversion pictures - and what happened when it was put on brake test rollers to test the brake efficiency for it's 12 month MOT test
    Able Engineering (midlands) Ltd - Home | Facebook
    Under 1 of the previous pictures on this site is an A4 piece of paper stating the T&C's from the supplier of the kit, absolving them of all legal comeback etc,
    before we release our disc brake conversion for general sale we will have to consult somebody legal to confirm if this can be done.
    Steering Ram parts now being made !!
    It's Peterborough LRO show this weekend, hope the weather stays dry.
    Here is another 1 of Martins toys based on an ex MOD Bedford 16 ton (32 ton war load) troop carrier chassis - with a higher 5th gear fitted in the gearbox, 70 mph is possible, tyres are the limiting factor !!
    Cheers

    How to fit Disco Servo?

    Homestar,

    What is involved with fitting the D1 Servo on the FC101? Which master cylinder did you use? Your reply is greatly appreciated.

    Cheers,

    Steve Moore

    Hi mate, when it comes to brakes I’m of the opinion you really need to be confident in what you’re doing and happy to do it. Disco 1 booster only needs a few small mods to fit - as does the original master cylinder. If you pull it apart and lay it down next to the new one, it becomes quite apparent.

    Sorry for not being more specific but I’m sure you’ll understand why I’m being a bit vague.
    If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.

    D1 Servo Reply

    Thanks for your reply. The D1 Servo appears to be bigger in diameter and thicker. Did this present any challenges? Do you know the bore size of the FC101 master cylinder?

    Diameter makes no difference to the fitup, but makes getting the speedo cable to work challanging - the thickness means the master cylinder sits further forward but the original pipes still bolt up fine with a bit of finagling. No idea what the bore size of the MC is sorry.

    Also, make sure you seal the MC to the booster with a gasket - you'll have an almightly vacuum leak if you don't.
    If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.

    Servo Adapter?

    One more question if I might? Did you have to fab an adapter plate between the servo and the pedal box? Or did bolt straight on?

    I can't honestly remember.

    As I mentioned at the start, if you aren't confident in doing a job like this - please don't do it. Mucking around with the brakes on a vehicle is potentially very dangerous - I take no responsibility for what you do and what happens sorry - by the questions you are asking, I would suggest that this isn't something you should be doing to be honest.

    Maybe if you started a thread on your 101 and showed us what you can do, or had been on this site longer, I'd be prepared to share a bit more, but all your posts have been short and with no explanation of what you have, you engineering and mechanical skill levels, etc.

    I don't want to be responisble for a second rate conversion that may fail in the future sorry.

    If you're up to the task, go for it - you'll figure it out. And ask an Engineer first if it is legal in your area - another thing I have no idea about as I don't know what area or Country you are from.

    Appologies for being so blunt, but I'm sure you understand.
