Calipers cause confusion....

Finally made it up to the garage last night with good intentions of fitting the calipers and shimming the rear brake discs.

However as always things conspired against me and I didn't get half of what I wanted done. I did manage to temp fit the rear discs with no shims.

However when trying to fit the caliper bolts through the problem occurred.

This is as far as the bolt goes in, in fact I gave it a little tap with my hammer and that jammed it in solid! Luckily I was able to get it out with the press but if I didn't have that it could have gotten nasty!

I managed to fish out on of my old bolts and when compared you can see a difference.

By measurement the new bolt is 11.16mm in diameter vs 10.8 for the old bolt. The hole in the caliper is around 11mm.

The old bolt fits OK in 3 of the 4 holes in the caliper but still does not quite fit in one.

A few emails to Ed at Wards and a quick conversation today and I am informed that Jaguar used 2 suppliers for their calipers for a while, this one used a slightly smaller bolt hole. Jag, in their wisdom, only have one part number for the two different bolts required. Ed is going to send me some new bolts to try.

Ill let you know how it goes!
