The brake fluid is DOT4 (and should be changed at a 2 years interval).
The Alfa OEM brake disks are made by Brembo ... don't know if they are superior to EBC but they are premium quality. My brake pads are made by TRW (a lot of components in Alfas are made by this company) and are very very good. Braided brake hoses ... apart from looking neat, there is not enough pressure in the braking system to need such tough components. If you do replace them, make time to take apart the callipers and give them a good clean, especially the sliding pins.
