Please forgive me for asking a potentially stupid question, but I want to make sure that I order the correct parts.

There appear to be two different types of front brake rotors for the 2005 Devilles (brake code JL9). The online parts catalogs list them as:

To VIN # 1G6KD54X25U129028 (for example the ACDelco #18A813, GM #18038817, 19175050)

and

From VIN # 1G6KD54X25U129029 (for example the ACDelco #18A2498, GM #19203682)


My car's VIN is 1G6KE57Y85U106380. I figure I can ignore the differences in the VIN (such as KE (DHS) instead of KD (Base Deville)) and just look at the production sequence number, is that correct?

All rotors are the same for all last gen Devilles except commercial chassis. Any 5 lug rotor listed for your car will work.

Yup ^^^

Take a look at the different AC Delco choices in www.rockauto.com.

If you can stand bewildering, surf through the options for your car in www.placeforbrakes.com. (Free shipping on 75 pounds of cast iron is a deal ................[that's all 4 rotors])

I would suggest that you replace ALL the rotors and pads with the same brand/performance level. Different rotors and pads DO have different braking abilities.

Remember that the rear caliper pistons screw back into the caliper. Do you need brake pad wear sensors, too ?

Yes, commercial chassis (J55) has an entirely different rotor, but there are still two different versions listed for the regular JL9 brakes.
It looks like they changed the front rotors during production of model year 2005.
For the 2004 model, there is only one type listed, the "earlier" one.

Yes, that's where I'm looking.

I intend to get ACDelco Professional Durastop's as I already have the Durastop pads.

Yep, thanks for the info. Other than the mechanical scratching thingy, there are no pad wear sensors on my car.

Based on the info you provided and confirmed on RockAuto it appears there was a mid-year production change at the VIN break above. Based on your VIN... go with the first set.

You are correct... No difference in rotors from a KE (DHS) and KD (Base)... they are both non-heavy duty, 5 lug rotors. Just look at the production sequence number (last 6 digits of VIN).
