Hello all,
My sons 1986 300D brakes started acting up about a month ago. As the brake is depressed, and just before the car comes to a full stop, the front brakes "chatter" and brake ability is reduced, you can feel the "pulsating" through the pedal. Pretty scarry ...
I've removed the two magnetic sensors ( which were totaly full of brake debri) and cleaned them and reinstalled them.
The problem went away, and the drake system acted normal - for about a month...
The problem is back, the sensors are clean, and I've sprayed inside the hole with brake cleaner, but it didn't fix anything, it's still doing it.
Any ideas ???

Thanks: George
