Hello Michael,
Yes, The GTD40 used Granada/Scorpio brakes as you say. Like many others though, I threw mine away and fitted much bigger brakes. Why not miss a stage and not fit the GTD brakes ? My car now has 320mm vented disks back and front, with 4-pot calipers, all made by Willwood. I have a pedalbox with a 6:1 ratio and no servos. Both front and back master cylinders are 0.75 inch bore. The caliper bores on the back are smaller than the front as a crude brake proportioner, and I have an adjustable bias on the pedalbox, which may not be legal in your country.The '40 now stops, every time ! My worthless advice is to go straight to big brakes. Another potential pitfall is the handbrake. You will either have to fit an additional spot caliper, or fit an hydraulic handbrake (quite simple) or use the Granada setup on the back.
Tony.
