The thought did cross my mind but they were purchased from a reputable supplier, one of the UKs biggest (Eurocarparts) and the box did have a hologram security seal on it but that probably means nothing.

 

Did you contact Pagid? They have a good reputation and I'm sure they would be interested in knowing and/or helping.

Best.

 

What he said...

 

I spoke to Euro car parts who said that Pagid offer 24 months warranty and would not do anything outside this window, I have still to search for the original receipt.


I couldn't find a contact email address on the Pagid UK web site and the "Help" button takes you to a Eurocarparts live web chat.

 

I would post on their social media wall or contact the US support if that doesn't work:

I found the receipt, October 2012, not sure I will get anywhere with that.

 

I have been using the CENTRIC POSI QUIET Ceramic pads on both the XK8, the XJR and a previous XJ8. They are quiet and absolutely minimal dust. No bedding is required. Check them out before your next purchase.

 

Thanks for the update and clarification of pad material thickness. I do agree with you that with that much material remaining they should not have detached from the backing plates.

Whether it's a rare one-off or worthy of a mass condemnation of a well known vendor, I'm not sure.

I see also that the piston was not jammed. How were the pins that the caliper slides on?

 

The pins are good. If I get bad service from any supplier in any walk of life, when there are plenty of good alternatives, I don't go back to them.

 

How is it behind the bushings where they sit in the bracket?

A somewhat unknown problem is corrosion in the
holes that causes the bushings to pinch the pins and thus
limit movement of the caliper relative to the bracket.

 

Depending on your viewpoint on life and the culpability of the
manufacturer, the workaround is to buy another identical set,
keep box and receipt, return in six months.

Only you can judge whether you are comfortable with doing this.

 

I put plenty of grease on the pins when I did the pads last time so they slipped out easily.

 

Good idea unless the new set also delaminates in 3 years....

 

I meant the bore surrounding the outside of the rubber bush itself.

Water gets in there and corrodes the ally. The crusty stuff swells
and squeezes the bushing down.

I had plenty of lube on the pin and all seemed well, but problems
persisted.

Then the owner of the shop who was quoting on turning the rotors
mentioned that problem area in relation to brakes not releasing.

After popping out the bushes and some work with abrasive paper
... much improved freedom of movement.
