vin no.yv1245847f6650723,,turbo petrol estate.with solid rotors on the disk brakes.i need to replace a front disk brake caliper,but need to know which brand.any help is much appreciated...cheers from down under[oz].

 

Vented rotors in the front probably means Girling calipers. My Turbo car has ATE calipers in the rear. Not sure if they are non-vented rotors in the front.
