Not sure what you are flying, but if it has any performance to it you should be aware of the antilock systems pulsing when the brakes are releasing. In the 560SL you will feel the pulsing in the pedal as the computer releases the brake pressure to that wheel.
It could be one sensor giving the computer a "lock up" signal so that one wheel is releasing. The ABS light will not come on when the system is "working" as designed. The wires to the wheels are known for breaking and needing to be replaced. But usually the ABS light will come on for this failure.

Another common problem are worped rotors. As you slightly add brakes at low speeds you feel a pulsing in the car that slows it frequency as you get slower and slower. This is a worped rotor that is caused by heating the rotor in a hard brakeing situation and then leaving the pad agains the rotor once stopped at the light or stop sign. You have to replace the rotor in this situation. They can be turned at a shop but the woped rotor will return in about 5000 miles.

Do the brakes feel like the power booster is going bad. This would feel like you lost the application abillity pressure. The brakes would work but you would have to press harder than normal to get the same braking effectiveness. Your booster is the "power boost" supply to the brakes.

Consider taking the car to a independent or dealer you trust. Robert Schnider at ******** is a good guy, Ive known him since 1981. Zims, right next to Park Place Mid Cities is a good shop also. they have worked on my 560SL
