Hi Guys, brake caliper placement on the front axle is determined whether the car is Front wheel drive (East / West or side to side engine orientation) or rear wheel drive (North / South engine orientation. Front wheel drive calipers are at the front of the disc because the steering rack is behind the engine and so the tie rods connect to the steering knuckles at the rear, where-as rear wheel drive cars typically have the steering rack towards or at the front of the engine so the tie-rods connect to the steering knuckles at the front which means of course the calipers are positioned at the rear of the front discs. Rear brake caliper placement is more about suspension / rear axle design and where they fit best.. Hope this helps.
