SLK350 disks & pads, what size?

[Colin_b]

I'll need to replace the pads and disks on my 2007 SLK 350 in the next few months, so I thought I'd order them early.

Went to Euro car parts, put the reg no. in and away I go. Except I have a choice of 2 part numbers for each component.

ie, rear disks, both Pagid, 2 slightly different sizes...

How do I get the right size....

Get them to look them up properly!

Or get them from MB. They are not as expensive as you may think.
