Just a thought from the previous post and the illustration from halfords - showing a 7mm allen key as "bought with"- not sure of the Jaguar arrangement but on the Honda the allen socket of the slide pins was indeed 7mm. I have a good selection of allen keys but the sets seem to skip between 6mm and 8mm so I had to decamp in mid job and buy an expensive set from Machine Mart to complete the job.

Yes - needs a 7mm Allen key.

Shoulda gone to Spec-sa - - - -. A proper tool supply shop who would have sold you one 7mm Allen Key, for the use of, and not expensive.

7mm is a strugg size in normal sets, but easily available separately.

Not sure where previous poster resides but in an area without many small engineering workshops the concept of a "tool shop" is something of the past. Individual items like allen keys are readily available on the web for little money - however most places like halfords and machine mart only keep them in sets and these mostly seem to miss out on 7mm.
With the car partly dismantled I chose to pay over the odds rather than reassemble and await the post.
At least I know now my 7mm will fit the XE when the time comes.

About the windback tool do check compatibility as when I found my existing tool had the wrong spacing a trip round all the usual suspects found they were all identical to the one I had.
Were I now starting from scratch I would probably get the one mentioned above with the clever adjustable spigot spacing

Try the likes of Cromwells (other Cos do exist) they have depots country wide. Yes I do deal with that sort of place, though no longer on a daily basis and I do admit they will not be found on the usual High Street, you do need to look for them.

Yes - did their search and we are midway between Bristol and Birmingham branches. I well remember that sort of place years ago but am afraid they will only be in big conurbations with an engineering bent nowadays.
The internet is very good for picking up obscure tools (crow foot spanners for example) but not much help if the need is urgent.

These are also very good, https://www.screwfix.com/p/teng-tools-t ... -7mm/4338x if a tad more expensive.

This looks a really good tool. I like the left and right handed thread arrangement. The only thing you need to know is which way round to turn the piston. i.e. left or right. I bought a much cheaper tool than this a few years ago, when I did daft things like changing pads and discs myself and had to decide whether to buy a left or right threaded tool.
Dont suppose you know which needs winding left/right?
I wish I could help you Steeveyboy but I don't know the answer. Perhaps someone on the forum can tell you which way to turn the brake piston. I found this on YouTube, it's for the XF, but it may be useful for the rest of the job. https://www.youtube.com/watch?v=KyETtzM2veY
Thanks Bazza

Hope this helps identify how to activate the EPB.

Superb! Really appreciate the confirmation. I take it that when the car shuts down whilst in this mode it does not activate the epb? No doubt will find that out very shortly!
