They use DOT-4. You can use DOT-5, BUT you must first remove every spec of the old stuff and make sure nobody ever tops off your master cylinders with DOT-4 or DO-3!!! If you mix 3 or 4 with 5, they react and form a mess with the consistancy of cold jello.
Specwise, 5 is about equal to 4 but might have a slightly higher boiling temp but, it is silicon based so it doesn't eat paint.
