[SEl] - Interesting Brake Pad Wear Sensor Technology/Information

[Dave Rotigel]

Hell, the sensors do NOT have to be expensive. My MB '79, '84 and '86 had 
them on the front pads. They cost about $1.40 each when the time came to 
replace the pads. All they did is ground in order to complete the circuit 
when the pads needed to be replaced. It's about time that other car 
manufacturers came into the 20th century!

PS, Next lets talk about the wipers on the headlights. I laughed like hell 
when I first bought that MB--but after driving it for one winter I realized 
just how good those MB engineers were!
