Part numbers

Oldtimer-Ersatzteile24 MB-107-4200-S1. Cross-references 1074200183, 1074200083, 0034212598, 0034212498, and several others.

Fits

Built between March 1980 and August 1985 only, ATE 2-piston system, 60mm piston diameter, for 22mm discs. Explicitly does not fit cars built before February 1980 or after September 1985, those need a different caliper, not yet sourced. Given how narrow this window is, a VIN check matters more than usual here.

Why it matters

Seized or leaking calipers cause uneven braking and premature pad wear, and on a car that may sit between drives, caliper pistons seizing is a common issue. A complete caliper set solves it properly rather than patching one side.

What you get

Front caliper set, left and right, complete units, not a rebuild kit.
