Well, it looks like your booster is okay. But the boot is torn. That boot goes around the shaft that connects to the brake pedal and then into the booster.
From what I am told by the MB parts department it is not separate. You must do the whole booster.
The cost of a booster depending on what options you have can be from about $484 to $540. I just went to a web site I get MB parts from and they wanted about $600 beans. So in this case the dealer was cheaper.
To me Ted, unless the booster gives you problems I would leave it. Now you can get rubber glue and try that but I think it will tear in another place. You have a few miles on the ML which means it has been good to you. If you think how many times brakes are applied daily, times weekly, times yearly.I am surprised they last this long.
My advice. If you do decide to change the booster.I would change the master cylinder also. Will it cost more. Of course. But you have to take the master cylinder off anyway. It has just as many brake applications as the booster. It is only a matter of time.
I hope this helps.
