The w123 uses fixed calipers, not floating, correct? About the only reason a fixed caliper seizes up is neglecting the brake fluid service. In a moist climate like WA, following the MB schedule of complete brake system flush every 2 years (regardless of mileage) is essential, otherwise water builds up in the fluid and rusts the entire system from the inside.

Yes the brake pads can sometimes stick in the pad box after sitting a long while, but they'll usually free themselves after driving a few miles.
