rear NS brake caliper for GTV

Not sure if it matters, but ive got a 3.0 V6 p2 gtv, the calipers red at the moment, colour is unimportant as long as the caliper is good..

may be the same as the calipers on the 2.0 twinny or the 156 etc??

had braided brake lines fitted and the MOT place reconns the bleed nipple has been over tightened by the company that did it, so fluid is pis**ng out...
