The Borg Warner (Chain Drive) transfer box, fitted to some Range Rover Classic vehicles have a piece of the casting which sticks out of the back of the transfer box where the PTO cover would be on an LT230 Transfer Box.

The Range Rover / Discovery brake partially covers the PTO cover. Therefore the Range Rover back plate interferes with this casting on a Borg Warner box.

Additionally, we have found several different orientations of the mounting bolt holes on the rear of the transfer box on to which our back plate attaches. So many in fact that if we made a back plate that covered all the options, all the holes would join up to form a slot!

I still want to fit an X-Brake! What do I do?

If your vehicle is a Defender, a custom hybrid or a 2 door Range Rover, you may be able to fit a Defender X-Brake which is compatible with PTO's and thus does not interfere with the Borg Warner casting. On a 4 Door Range Rover or Discovery, the rear passanger footwell is too close to the top of the transfer box. In this case you would need to cut a hole for the X-Brake caliper to poke through.

There is still the issue of the mounting bolt holes possibly being in the wrong orientation. The only solution is to re-drill your own holes. If you decide to go down this route, follow this simple procedure to accurately position the new holes.

1. Take a photocopy of the original Back Plate and mark the position of the original skid plate which hangs vertically below the disk.
2. Cut out the photocopy so you now have a paper Back Plate.#
3. Offer up the photocopy with the skid plate at the bottom.
4. Press your thumb into the bolt holes in the transfer box causing an indent in the paper.
5. Remove paper from vehicle and lay on top of original Back Plate, lining up the marked position of the skid plate.
6. Use a centre punch to mark the position of the thumb indents on the Back Plate.
7. Drill 10.5mm holes at the centre-punch positions.

This method is surprisingly accurate (it's actually how we made the very first X-Brake). You should now be able to bolt it in place. If it's tight, just enlarge the new holes a little to compensate.

Many customers have carried out this procedure successfully.

I have no tools / interest in this kind of modification. What do I do?
You can return the kit to us. So long as it is un-damaged (particularly the bolt holes in the back plate are un-marked), we will refund you in full less the shipping cost. We will deduct the cost price of any missing or damaged parts from the refund. Please include a note in the box giving your contact details and why you are returning the product. We hope that if you have a compatible vehicle in the future, you will consider an X-Brake for it.
