Late E500 braking system question

[BlitzenBenz]

All,

Does anyone have knowledge of or documentation regarding late E500 braking system characteristics and equipment? I own a '95 Euro E500 (originally delivered in Germany) and recall having to jump through hoops to find a replacement brake booster as the original had failed. I remember learning (read it on a dealership service computer) that my car has unconventional brake proportioning: it has a 50/50 front-rear bias up until either the onset of rear wheel slip, or in high speed turns at which point it goes to a more typical (maybe 70/30?) proportioning. The car definitely dives less under braking than my '92 car, and benefits from the larger brakes both front and rear.

Any information appreciated

The late Euro models have the switchable proportioning valve as you describe... different MC, booster, vac pipe, ASR/ABS computer module, and a sensor under the rear seat. Probably something else I'm forgetting too.

A general description is in the FSM, Group 42-0700, section F. It's a real shame MB didn't use this system worldwide (USA and Japan didn't get the upgrade).

Many thanks! I’ve long wondered about the fluid filled sensor under the left rear seat-I’d thought it related to the security system though. Oddly, this car has a switch that allows the car to be locked and towed but not activate the alarm. I’ll post a pic of that switch
