Known issues on the 1992 G20. Owners have logged 36 complaints against this model year, and they concentrate: nine on the service brakes, seven on the power train and four on the seat belts. That pattern points at the parts of a heavily loaded van that wear first. Brake hydraulic overhaul procedures, master cylinder and booster specifications, transmission and rear axle work, and restraint anchorage torque values are all set out here, together with the diagnostic sequences that lead from a symptom in any of those systems back to its source.
