2007 e320 cdi sport front brake caliper problems.

[boxer 01]

Hi I was wondering about the best way of identifying which type of front brake calipers are on my vehicle as I require a couple of dust seals for pistons. I know its a 4 piston caliper and the piston dia. is 44mm but actually finding out the make and part number is proving very elusive. I have seen plenty of kits that have these seals included but they dont seem to quite match my dimensions.
I would be grateful for any advice.
Thanks

If there Brembo there will be a Brembo logo on the inboard side of the caliper near the brake pipe.

I was hoping somebody would point me towards some literature maybe a parts list for this model of mercedes. Thanks again to streethawk for advice.
