Doing the conversion to oem BBK and just had some questions. I can't seem to find out how many brake wear sensors are needed. Does each caliper get a brake wear sensor? I have checked ebay and on some e55 w211's I see only one sensor on a front caliper and one on the rear.
It appears I have two for the front calipers, and one for the rear. I have taken pictures of part numbers that I have. Does anyone know where I can get the actual harness that the wear sensor plugs into? IE: The harness that plugs from the car, attaches to the caliper and then the wear sensor plugs into the harness? Doesn't seem to be a common thing on sites, where I can find the ABS speed sensor harness but that isn't the same.


One last note, I have taken a picture of the bolt that the harness attaches to the caliper. I only have 1, and need 3 more. Does anyone have a part number for this as well?


The last few pictures are of the harness on the caliper, is this the correct orientation?


Thanks,

I am about to do the brakes on my CLS so subscribing. I was under the impression that there should be a wear sensor at each corner, no?

Do you have (2) sensors at the Fronts..?,

as i know; E350 got (1) sensor at Front Right & (1) sensor at Rear Right..?!?,

and E55 uses (2) L&R sensors at Fronts, and (1) at Rear Right,

why you need to get wear sensor harness..?, your E350 uses the same harness with E55..!,,

*harness (M6X20) bolt #: "N 910143 006002"

Excellent that is the information I wasn't sure on because I have three harnesses here for the e55 calipers but wasn't sure if the e350 used the same plug.. I haven't gotten the car in the air yet to start taking things apart. That's excellent news then! I looked at the harnesses on eBay for the e350 and they looked different from what the e55 has since the caliper is physically different. But this is good stuff.

I'll take picture hopefully this weekend to help anyone in case they are doing the same thing later one. This doesn't seem to be common so I'm just searching for as much info as possible.

w00t w00t!

Looks like those calipers you bought not specifically for E55,,

cause the harness got A220 part #, which refers to 2003-2006 "W215 Cl55K or W220 S55K..
