Brake upgrade for S2

[kiwihead]

I'm planning to fit a Cossie 24v 2.9 engine to an S2 and want to make sure it stops as well as it goes(!) One query is about the brake master cylinder, which needs replacement anyway, (as does the servo). I believe the master cylinder is a modified Saab unit (Saab 900?) for which I've been quoted £400, which sounds a lot. Has anyone out there fitted an S3 or S4 brake master cylinder and servo, which I believe are cheaper Ford units, to an S2? Any hints??

Also, I've been told that the complete set of discs and calipers from the Granada Scorpio that was the source of the cossie engine would be a straight swap into the S2, and all I would then need would be the V8S handbrake. Has anyone out there in cyberspace done this?

Any advice appreciated. Thanks in advance from a new member!

I have a nasty feeling that you need to swop the trailing arms to run the disk-hubs. I may be wrong, so I am sure that the others will let you know.

This has been raised before, so perhaps a search may give you the answer you are after.

one major difficulty is that the granada has a 5-stud hub, and the S only 4-stud, so unless you also want to renew the wheels, it's a non-starter.

The S brakes are sierra based (I have already fitted sierra disks and pads at the front, and sierra shoes on the back) so maybe sierra XR4i or XR4x4 are a better bet?

Thanks, TVRG. You remind me that Roger Folkard had described fitting 260mm XR4I front discs and calipers which bolt straight on (p38, March Sprint)

for the later scorpio models ford went back to a four stud fixing ...

For what it's worth, on an F-reg S2, I'm reliably informed that the brake master cylinder is from a Fiesta 1.6 CVH (89-94), part number 6170668.
Found this out yesterday as mine has died. :-(
