These pieces of spring steel actually have wires coming out of them and connect to the check light system. When you have worn your pads down to the point where the sensor gets grounded with the disk you get a nice warning light inside the car. Then you can say something like, "Oh my, I forgot to change my brake pads." to your sweetheart who is sitting beside you and who you have really impressed with your smarts on the car you are driving. But this is kind of silly and would never happen, would it? Especially if you're like the rest of us and perform maintenance on your car religiously. So what it boils down to is they are kind of useless. But then a true bimmer fanatic would disregard the previous statement on usefulness and get them anyway just take comfort that everything works. Personally, I have left them out just so I don't get embarrassed one day.
: I have been calling around looking for the best price for replacement pads for an 86 528e and many of the places I called asked if I needed the sensors too. From my old Chevy days, wear indicators were included with the pads...nothing more than a piece of spring steel. But these guys quote me prices like $14 for "sensors".
: Are they talking about the same thing I am remembering from my old Chevy's? What kind of sensor do these cars have that cost $14?
