    S2 Break Servo removal tips and tricks

    Hi
    Unfortunately my S2 coupe break servo has failed. Omicron are reconditioning one for me, so today I put on my big boy pants on and tried to remove my old one.

    Can anyone tel me how the hell to disconnect the Servo shaft from the break pedal. There's a large nut which will not shift, if this is that a locking nut it's doing its job.
    Theirs a split pin which doesn't seem to do much, should I remove it?

    I have sprayed it with oil and will attach it again in the morning but any advice would be very welcome.

    don't push on until you know what you're taking apart there. that could be a linkage rod adjusted to a very specific length. if you extend it too far the brakes may not release.

    If you look at the linkage of pedal lever and booster rod, there is a small cotter pin which you have to remove. Then you have to turn out the cap secured by the cotter pin (almost completely) with a screw driver. After that you will be able to to release the socket from a ball pin by moving it sidesways.

    Thank you for this information, I now understand what I need to do.

    The locking nut is large flat item, you need a large flat bladed screw driver to undo the 'nut' after you removed the split pit on the pedal, then you can pull off the joint off the top of the pedal.

    As mentioned before measure the rod length and note the hole is elongated in shape too.

    Hi Thanks for the information,

    I did find this video that is very helpful when it comes to checking and setting up the pushrod clearance.
