Yours is a Mk1 Tipo with (presumably) 13" wheels.
As standard the Mk2 1.4 and 1.6 Tipos had improved front brakes, you could go down this route (still OK with 13" wheels). Or you could go with the disks and calipers etc from the bigger engined cars like the 1.8 or 1.9TD (if you've got 14" wheels), stick with the standard drums at the rear (just clean them and adjust them).
I think the brakes of Tipos are basically the same as for the later Bravos and Bravas... the 1.2/1.4/1.6 were OK, and the bigger engined versions had bigger front disks etc and sometimes even rear disks.
Don't upgrade too much though... the Tipo will lock up its front end quite happily with standard brakes....
