  • Brake servo

    My Roadster was built twenty odd years ago and I rescued it after ten years standing, doing a rolling restoration. The brakes were reasonable until I replaced the rotten vacuum pipe. Then they were vicious locking the front wheels at the slightest touch. Now they seem to be working Ok with a bit much bias to the front. Question: Is the brake servo really necessary? Second re exhaust heat, a 'man in the pub' remember them? told me that it was a bad idea to wrap cast iron exhaust manifolds in tape because they get too hot and break. True or false? While I have the engine and box out it is a good time to fix things.

    The bloke in the pub is correct. They get too hot and crack.

      Cheers for that Jon. It seemed logical to me too.

        I'm busy building my Marlin
        But I took a dislike to the Marina pedal box and I have built my own using two master cylinders and no servo

        That is a lot of work - but I would suggest you do what my mate did back in the 80's with his Marlin

        He fitted a remote servo on the rear brake lines - this was with a Triumph Marlin so it did not have a servo before that
        You could fit a remote servo in the rear lines and simply disconnect the suction line to the existing servo

          I did look at floor-mounted pedals with two brake m/c and an adjustable balance bar but I am happy enough with the brakes but a proportioning valve on the front line might be a good idea.
