Here you see the clear plastic reservoir for your brake fluid in your W123. Take a look at it to see the level of the fluid and the color. If it is dark, consider flushing it out with new fluid. There is a guide for that on the main W123 device page.
Take a close look at the front of the reservoir and you'll see the MAX mark. The fluid should not be above this line. If it is, you can extract a bit of fluid with a plastic syringe that you can get at your local auto store.
