1994 Mercedes-Benz S500 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1994 Mercedes-Benz S500

Problems with the pneumatic system can cause closing assist and door lock issues.

The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors.  The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).

Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.
