Brake Master Cylinder - Saab 9000 type - Solution !

[Rower]

The Saab unit was used as well as the Fiesta Mk 3's on later S's , the Ford unit is I think fairly easy to source but the Saab is difficult or even impossible to find . However I discovered a small company located in Suffolk called Past Parts (www.pastparts.co.uk ) they specialise in re-building Master Cylinders etc for older vehicles , I sent mine to them and they re-sleeved it supplied new seals and then returned it to me, it is now fitted and I have brakes .

My job did take a while, because I sent them the seized Cylinder without the Servo attached ( it is now apparent that the Girling made unit was never supplied on it own ) when it was all put back together the pistons were not retained and just pushed out of the Cylinder, it needed to be fixed to the Servo unit which of course retained it , Past Parts got round the problem by putting in a removable pin which kept it all together in transit and was then removed by my Mechanic when the Cylinder was bolted back on to the Servo .

I was in contact with Nigel who was very knowledgeable and would definitely recommend the service I received.

If you are comfortable replacing seals yourself you can get a set from BiggRed here:

As Rower pointed out though, you need to figure out how to retain the pistons. The pin is a good idea if you have one to fit. Alternatively, two pairs of hands, as in my case, managed to guide the cylinder back in place manually, engaging the leftmost seal as we went.

I do not know if yuou noticed, but the end of the servo rod which makes contact with the master cylinder piston is adjustable, but preset at the factory. That is to get the optimum position of the cylinder piston. That is why they were sold as a matched pair and why owners need to be a little careful when changing one of the components only. I do not know for sure but I believe not all aftermarket cylinders have the same flange thickness.
