Ok, I've spent an hour researching this here with no luck... if anyone can help, please do.

I ordered a pair of rear brake calipers from Phil for my '91 420SEL. It has ASR, so I was aware that it incorporates the pad wear sensors. I specified this to Phil and he sent me the stuff. When I got the calipers (pre-loaded rebuilds) it appeared they would not accomodate the sensors. I wrote to Phil about it and he responded that he was not aware of a special rear caliper for ASR equipped models.

I decided to do the brake job today, and indeed, found that the rear calipers on my 420SEL are different than the ones Phil sent me. I looked on the Fast Lane website and don't see any calipers listed specifically for ASR vehicles, although they do have brake pads for them.

My existing rear calipers appear to have a fixed flange built onto them to accomodate the brake sensors. Doesn't look like there is any way to take it off and attach it to the new caliper.

For anyone who knows what I'm talking about, what am I missing??

Thanks
