Can anyone tell me if they have used the actual mk2 sharan rear calipers on the t4 and not just the carriers and disks. My standard calipers are shot and ive got the full rear set up, I was going todo them when i did fronts at the weekend but the routing and mounting for the flexi is different standard is bottom the sharan is top. Realy i want to use these ones as there in excellent nick than go buy some new t4 ones. thanks for the help in advance
