RobW 0 Posted December 31, 2021 Hi, I'm new to this forum and I've been having trouble with the search function. I'm in Australia and I need to upgrade my brakes to dual circuit. I believe some 'export' models had dual circuit brakes. Can anyone here guide me as to where I might be able to get a master cylinder for the conversion? Cheers, Rob.

mk2sav 42 Posted December 31, 2021 Hi Rob - comes up quite regular on here and other Cortina pages . You can use a Land Rover cylinder but if you are fitting it direct to pedal (not on a long tower as per some export markets ) , the fittings are horizontal and not verticle . Fords did make an adaptor to overcome that but where you could get one of them is going to be a challenge . If you search "dual circuit " on here , some pics are still on there . Steve.

RobW 0 Posted December 31, 2021 Thanks Steve. I'll have a bit more of a poke around. So I'm guessing there's not just a part-number for a dual circuit master that fit's straight up? All good. Quote Share this post Link to post Share on other sites
mk2sav 42 Posted January 1, 2022 Hi Rob - no , as far as I know there is none that fit without the adaptor as I mentioned . I have been trying to find a pic but no good yet . Steve. Quote Share this post Link to post Share on other sites
sheffieldcortinacentre 753 Posted January 1, 2022 Not sure but think the MK1 escort had it as an option? Quote Share this post Link to post Share on other sites
mk2sav 42 Posted January 1, 2022 Yes , Escort one is similar/same but still horizontal . Found a pic of the adaptor .Some USA cars had a vertical mount but again , not easy to find !! Quote Share this post Link to post Share on other sites
RobW 0 Posted January 2, 2022 Thanks again for the advice. This looks to me like it will fit? https://www.wilwood.com/MasterCylinders/MasterCylinderList?group=Tandem Remote Master Cylinder Quote Share this post Link to post Share on other sites
mk2sav 42 Posted January 2, 2022 lLooks like it would fit and while searching , found a pic of one that was apparently used on a Mk2 but why it was taken off I dont know . You would have to check with Wilwood about the bore size as 1 inch is quite a bit larger than standard . Quote Share this post Link to post Share on other sites
MLI 8 Posted March 17, 2022 (edited) 1 inch bore size will need the kick of a mule to stop it, it will be like stamping on a solid pedal... Try to find a dual master from a 1968 "export" mk2 Cortina (it will have vertical bolt holes and will fit more or less straight on). Or find a dual master from a 1969-70 "export" mk2 Cortina, it will have horisontal bolt holes, so you will then also need the 90 degree adaptor, from the same type of car. Ideally, you want either 0.7" or 3/4" bore size, to avoid it beeing too heavy in operation (without a servo).
