You guys are nuts - I've clearly come to the right place
Mark, thanks for the pic, diff to be certain from a photo but I reckon that's exactly my set up. Can you just unbolt it and post straight away please
I presume that disc brake models have a larger servo and so Mk2/3 not really an option unless I'm planning on a disc upgrade (not in the least bit likely
Also, I presume later models had diagonal lnked systems (ie front R rear L together) whereas mine has two outlets for front, both off secondary chamber and just 1 outlet for rears off primary chamber so I'm guessing parts are not really interchangable unless changing every single braking component. I could be wrong.......
Now have m/c repair kit. This includes vacuum seal between m/c and servo which was completely absent from vehicle on dismantling. This could go someway to expalining lack of effective servo
Now rebuilding m/c and will fit to servo with new seal and pray. Not optimistic but I don't know how else to test servo.
Wish me luck or send further advice (or complete mk1 servo andm/c assemblys Mark)
