Question -
1) I would like to thank you for your assistance in helping me with the repair of the water leak in the washer reservoir. I replaced both grommets on the pump assemblies and also inpected all hoses. That did the trick and the leak is now fixed.
2) I would also like to remove the rear brake drums to inspect the park/emergency brake mechanism. After removing the wheels I find that the drums are extremely tight on the hub. Can you recommend a procedure on how to do this properly? Thank you in advance.
Note: Yes, I did not forget to release the brake pedal.

Answer -
Yes:
The typical windshield washer tank leak is caused by bad Washer Pump Grommet.
Locate the washer pump attached to the tank, carefully pull up on pump while rotating side to side, when pump is out, remove the bad grommet and pop in new grommet, install pump and fill tank.
Be prepared to replace the pump and/or hose also, with age they become delicate.
Mercedes Benz Nylon reinforced Washer Hose = 5 Meters; and
Hose can be replaced with rubber hose from your local generic auto parts store.
Here are the part numbers; but I suggest you check with your local MB dealer, they may be cheaper after S&H + minimum order cost.
If it is a crack:
The secret is to clean, dry and rough the outside of tank in repair area with medium sand paper, wire brush or abrading tool, then use canned (dry) air to blow clean, before applying any sealer.
I have used; hot glue gun, epoxy, super glue and many other products to repair the tank.
It may be cheaper for you to buy a new tank if cracks are bad.

AnswerRemove caliper.
On the face bolting of rotor there should be one recessed 6mm Allen screw (Brake Disc Set Screw), remove it.
Use a large rubber mallet or medium plastic dead blow hammer to separate rotor from hub.
In extreme cases you may need to use a five pound sledge hammer; be warned that this can wreck the rotor.
Replace Brake Disc Set Screws with NEW, if you plan to keep the car.
Replace Brake Pad Sensors if damaged.
