Front Disc Brake Conversion 750/101 Cars One of the vintage aspects of driving a Giulietta or 101 Giulia are the brakes. They are fine for normal driving, but can be a bit too exciting if you really need to stop fast. If you like to drive your Alfa, our front disc-brake conversion kit will make your vintage Alfa stop like a modern car. An added bonus is future pad and rotor replacements are easy! You need for the conversion: These adapter brackets, 2 litre front calipers, 2 litre front discs, brake pads, brake lines, 2 litre front hubs, new hard lines between the flexible lines and caliper, and new wheel bearings and seals.
