The check brake light is starting to come on/off on/off:

Are the warning sensors on the front only?

Is it recomended to do front and rear? OR only front if the rear looks ok.

Is the disk back plate anti-squeal grease speical?

1989 190E 2.6 only front brake has brake sensor,I'll use OE brake pads only.

I've had good luck with Pagid brake pads. I believe they are OE quality. The main thing is they don't squeek. I've seen Textar pads quiet most of the time but once in a while yu will get a set that will squeek and drive you nuts. Check the rotors, and if you need new ones buy them and the pads and sensors here at parts shop. You will top quality parts at an excellent price, with excellent service.

The sensors are front only and as long as the rear brakes look good, you do not need to replace the parts simultaneously with the front brakes.
