I tried looking at this but gave up as I think it might be a bit too risky for fear of locking up the brakes. In the end I put a new BMC on and bled the system with an Eezi Bleed. I'm going to re-bleed they system again with the help of a pedal pumper before my MOT next month. Should be ok thereafter.
Hi Mate...There is a section in the wedge workshop manual which will follow but first have you checked for pad wear..Leaking servo or contaminated/old brake fluid?...
Exact quotes from The wedge Manual.
ADJUSTING PEDAL PLAY
This is done by separating the reservoir/master cylinder from the servo unit to get access to an adjuster.
Two nuts hold the master cylinder in place.
These need to be un-done to separate the cylinder from the servo, There is normally enough movement in the brake pipes, So there is no need to undo them.
Between the two units are two rods, The first rod acts on the second and the clearance between them can be adjusted by a small bolt on the servo rod.
Excessive clearance causes the the play in the pedal movement.
The clearance can be adjusted-But it is tricky because this adjustment needs to be done by trial and error, Too much and the brakes will start to bind...Too little and the play can be increased.
Once the adjustment has been made the master cylinder is re-fitted and the two nuts tightened up, It may take several sessions to get the right value but it can make a tremendous improvement on the feel of (And confidence in) the braking system.
Hope this helps....Cheers...Ziga

I have had similar issues in the past, but over the years I have replaced the servo, front an rear discs, calipers plus pads and blead the brakes several times and I now think there is nowt wrong with the pedal now. I think its a case of make sure everything is working as it should first before you do that extra bit.
