Hey everybody,

The front brake pads as well as the discs are in need of change. So I went to EPC online to get the part numbers and came up with A2104210712 for the disc.

I went to the local MB parts store and the sales guy gave me discs with part number A2104212412. He assured me that they are compatible with my car when I told him that the part number I got from EPC online was different.

I checked online for the part number that the sales guy gave me and found this.

Looking at EPC online for this part number, I found no reference to an SLK. Could someone explain to me what is going on, as I'm supposed to have these changed tomorrow?

Thanks.

P.S. Although I live in Lebanon, my SLK is a US spec car.

Those should be OK.

If you write the part numbers out like this

A 210 421 07 12


A 210 421 24 12

You will see that the only difference is the penultimate field - 07 as opposed to 24. This field refers to the modification or variant number of the part. The numbers are actually random, so 24 could refer to an earlier or later version of the same part.

Yeah! what Woolly said!

I thought a penultimate is what you carry when it rains
