The Granada 2.9 24v (up to the facelift) uses the same calipers as the Sierra Cosworth 4x4. According to Microcat the front calipers on the Sierra 4x4 and Escort would be different. That would actually make sense I suppose, as the facelifted Granada 2.9 24v uses the same calipers as the Escort Cosworth.
The brake pads are also a different number for the Escort than for the Sierra 4x4. But I'm not sure what is actually different. For instance EBC lists the same pads for the Escort and Sierra 4x4, so the difference is probably not really important.
The number for the Sierra Cosworth 4x4 pads from TRW is GDB473. Hope this helps.
