There are a series of white inked numbers that differentiate right and
left with wear indicator and the outer two pads
R/H/F 453810 and 453824
L/H/F 453717 and 453824

The pads also looked to have lost quite a lot of thickness when I removed
them this morning. Measuring the friction material only not including the
metal backing, there is just under 9mm left on each pad, didn’t measure
‘em new but they look visibly thinner after only 1000 miles.

I asked the dealer the day the car was taken back in if they kept the old
pads or indeed if they had made a note of the removed pads make, thickness
etc and they hadn’t bothered.
When I worked as a mechanic we always gave any removed components back to
the customer as they were the customers property (oil filters being the
exception to this, unless they were requested, and some were!!).

The garage said the pistons were clean and free (but without checking
myself I can't be sure).

I will check the piston moves back in after the pedal is pushed and report
back.

One thing of note, when I did repeated emergency stops (around 5 or 6 of
them) on 3 occasions when starting off after stopping, the car pulled to
the left for a short time as if a piston was sticking.
The pads are easy to get in and out of the spring shims and don't appear
to be binding and the calliper slides all appear to be free (front only, I
haven't checked the rear as yet)

Thanks once again
