Paul, I did a lot of investigation around xr2 brakes when I did the Fiat 20vt conversion. Ford seem to have arranged their calliper pickup points on the hub to be the same through a lot of their models... on mine, to replace the xr2 brakes with Mondeo 2.5 V6 brakes (!!!) I needed only to drill out the locating holes to 12mm from 10mm (from memory) and a little machining to the hub face to move the calliper frame back half a mm to clear the discs.
I would expect that you would find the xr2 discs and brakes a simple bolt-on change - but I would ask if you currently have new parts fitted? New discs and pads make a fair difference to efficiency... you may have difficulty getting the correct mounts for the xr2 - lots of places will sell you callipers but not the frame. XR2 discs will fit under Neil On May 6, 10:04 pm, "[email protected]" <[email protected]> wrote: > Hi Can anyone help, I have just had my 2+2 IVA tested and failed due > to the service braking efficiency being low, 55% needs to be above > 60%.
