Brakes 200

Top up the reservoir first.

If the reservoir level is low, then you have leaks. The pedal is soft and brake failure light is on because there is/was a pressure imbalance generated when you are pushing fluid out of the system somewhere. Find and fix the leaks.

Once fixed, if no air has entered the system, the pedal may firm up and you can do a regular brake bleed. The seller has probably been topping up the reservoir so the fluid in the system may be relatively new.

If the pedal were dropping to the floor, rather than being soft, your MC could be defective (seals) or have air in it. But missing fluid doesn't point to a bad MC unless the rear seal by the booster is gone. So find the leaks before fooling with the MC.
