My 2002 Mercedes SL 500 door locking system and top operating systems stopped working. I was told that it may be the pump in the trunk, but need to know how to test it prior to replacing. I was thinking about bench testing it but there are many small vacuum/pressure lines coming out of it and I am not sure what will happen if I remove them..
Thanks for your help
I had this problem, the pump is very expensive however if you can not hear the pump in the car it is the motor that has gone down.easy to repair, I got the motor out of a 12v tyre air pump for the cost of £6. Be very carful when you take the pipes off. in my S class there are two pumps, the one in the boot is for the soft closure doors and there is another one under the back seat for the central locking. Hope that is of some help

Hello, When you are looking at the caliper, you should see two pins holding the pads in. Look for the holes or the ends of the pins and drive them toward the inside of the caliper until they come out. Then take a large screwdriver or large channel locks and pry the pads away from the rotor. Now you should be able to take the pads out. When installing the new pads, you will have to put the pins back from the back side until they are flush with the caliper. When finished, make sure you pump the brake pedal until it comes up to the normal level before trying to move the car.
I hope this helps.

SOURCE: how do i remove hardtop on a 1990 mercedes sl 500
Assuming the hardtop/soft top system is operating properly-push the red switch in the console towards back of car until the top pops up. Make sure you unplug the defroster harness at the r rear of top (behind passenger seat. It will take 2 people to grab the top and pull it up and off. If this system is inoperable- there is a tool in the tool kit(if not you can buy one at the dealer-called a hard top removal tool) and unlock the 2 locks in the front of the top by the sun visors, and 2 locks located behind the seats by the quarter glass panels and the 2 locks in the rear accessible through the trunk. Your owners manual will describe how to do this procedure. I hope i have been helpful
