W216 Brake wear sensors (2010 cl550)
Are all the wear sensors identical or do they differ from front to back?
MB lists
the front as
Wear Indicator - Mercedes-Benz (1715400617)
the rear asWear Indicator - Mercedes-Benz (2115401717)
I have been unable to find a reliable source to cross reference and some sights show all four corners as 1715400617. I have seen front kits that include two rotors, four pads and one wear sensor.
Any input is greatly appreciated. Thank you.
