    Rodolfo, or anyone else needing this, I just thought I'd share that a m12 1.00 nut is available for 3/16 (4.7mm)

    The problem with that is the internal diameter of the flare of the Tesla master. IIRC it is too big to use a 3/16 line directly. You canít flare a 3/16 line to that size reliably.

    Another brake nut

    I've used another brake nut, also for 4.75mm (3/16") pipe.

    It has thread all the way to the end. If I remember correctly the pipe seated well.
    At least I have driven it for quite a while without any leaks or issues.

    Did you install the actual master cylinder upside down on the booster?

    I mounted the Model S iBooster and Master with the plug for the iBooster to be on the top.

    EDIT: Actually, seeing the initial pictures of the unit as it comes from Tesla, yes. I unmounted the master from the booster and flipped it. That’s the only way for it to fit in the Delorean.

    @81dmc

    any chance you have more photos showing mods you did to fit ibooster to DeLorean? New or modified bracket? connection to pedal?

    I'm doing engine swap (#vin4454 on Facebook) and as my stock booster and master cylinder and dead, I wanted to use some modern unit (even bought separate vacuum pump from Golf!).

    However iBooster looks more appealing and used by even more OEMs so price is not that high comparing to NOS DeLorean parts!

    I want to do it! Do you also have power steering?

    kind regards,
    Marek

    Let me grab some pics when I get the time.

    For mounting, all I had to do is drill 4 new holes on the stock booster mounting bracket and bolt it on. Connection to pedal was achieved by buying a threaded rod, cut to size, and mount with coupler stock iBooster rod. I mounted the Tesla clevis to that rod with a bit to lock it in place. With that, the Tesla clevis will fit right up with the Deloreanís pedal.


    Also no power steering for me:/

    thanks for your quick reply!

    do you get full pedal travel ? or you think there is a bit left? Can you lock wheels at higher speeds if you press it hard enough ?

    thanks,

    Pedal travel is definitely less than stock, but that is why I even did the swap.

    If you nail the pedal, yeah you can lock up. The Tesla 50-50 master performs way better than the factory master imo.
