Is the Swift 1.6 Master Cylinder/Servo the same as the GTI / other swifts? Need one!

I have discovered that there is a fluid leak where the servo/master cylinder bolt together
Are parts interchangeable between the lower capacity Swifts or even the Vitara??

Edit : Just looked and it seems that a gti one wouldn't work as that is configured for disk/disk rather than disk/drum, which I have...

Thanks

Wouldent you be able to do the conversion like the justys? Get the rear carriers calipers and discs from a gti? Then u will be able to use a gti master
