Got the new clutch and new slave all fitted no problem but the slave is only moving ~1-2mm which makes me suspect that the master cylinder is buggered. I have had a search on here without sucess to try to find out what car the Sag master cylinder is off so I can source an up-rated alternative -> Wilwood etc, can somebody point me in the right direction?
Got a master cylinder from racetech in the end, bores on mine badly scored. Sag is in a bit of a sorry state at the moment, bits everywhere! Replacing the 3.46 diff for a 3.73 whilst i have to prop shaft off for the clutch & slave replacement. Looking forward to getting back into it!
Does anyone have a hydraulic schematic for the Sagaris? Im having real problems:
Slave cylinder (new) isnt moving
Master cylinder is new
Clutch pedal is very light - no resistance
Brake pedal is completely solid
Pipes from the clutch master cylinder and the brake master cylinder seem to go into a hydraulic distribution manifold but I'm not sure how that ports out to the relevant consumers as its all hidden away and I don’t see a reason to take it all apart just yet.
I have obviously bled it!
Ideas's and a schematic please ......

Assuming the new cylinders aren't faulty and there is no leak between master and slave, it sounds to me very much like your master is not bleed properly. They can be very difficult and it only takes a little air to stop the MS working at all against pressure. So you could open the nipple at the SS, pump fluid through, but as soon as the MS has to act against the true force of the clutch it can't generate pressure, hence feels light and SS doesn't move.
I've found the best thing to do is crack the pipe open on the MS output port and put a small shallow tray or lid under the port to catch the bleeding fluid. Once you're getting a steady stream of fluid with each pump (you may hear the air working its way out too) then tighten up the hardline output a 1/4 turn at a time and you should feel the pedal get a little stiffer. Then Bleed the SS out.
If that doesn't work get back to us.

Thanks! Sorted it finally after a frustrating day. I ended up taking everything off again and stripping everything down. I think it was the slave not seating properly/all the way down. Anyhow it works now so happy days!!! I've found the best thing to do is crack the pipe open on the MS output port and put a small shallow tray or lid under the port to catch the bleeding fluid.
