    Bias pedal box and servo

    I'm not completely lazy, I'm going to google and I'll report back anything I find but I'd appreciate first-hand info from anyone who's done it.

    I'm thinking about a bias pedal box for the 100E on the basis that I'm not completely sure what I'm doing with the rear brakes and I want adjustability. I've got 2.8 vented discs up front with Princess 4 pots. I'll have, at least, 9" drums but probably a disc conversion in the back. Trouble is, I've also got a remote servo but it's only a single channel (channel?). I have one line coming out of the Master Cylinder that goes to the servo, the output of which goes into a splitter (proportioning?) valve which also acts as a pressure switch to activate the brake lights. From this, one line goes to the back, and another two go to the front calipers.

    So, do I do away with the remote servo? Do I use it on the front/rear only or is there a 2 in, 2 out, cylinder I can use on the servo? Can I even change the cylinder on the servo?

    Cheers in advance, Jim
    One day, I might get to drive it again.

    In case anybody was interested, there is such a thing as a dual-circuit remote servo. Here;

    Nice one. I may try one on my next project. What do you do about vacuum with throttle bodies?

    Vacuum pump off an older diesel...like a Pug 205/309?? Might have to alter the gearing to cope with big revs...but it'll suck like a hooker on piece work!!

    No idea, hadn't got that far but I like the Pug vacuum pump idea. I was wondering if you could just use a different master cylinder (like the Wilwood one you're selling) on a boggo remote servo to do the same but I'm guessing there's all sort of reasons that wouldn't work else someone would have done it by now.

    Mine is a fast road car on bias pedal box so would the above servo do the job or would I need the twin set up? Thanks for reply.
