I was attempting to replace my front brake pad i removed the 2 allen wrench bolts anti rattle spring thing and a star type screw bolt thing for the sensor but the caliper wont come off need some help asap thanks reason asking is i think i might be forgeting something and i dont want to damage any parts

 

with the key off disconnect the abs asr module

 

where is the abs asr module? and what doea that module got to do with not able to remove the caliper?

 

remove the caliper mounting bolt from the back side of the caliper?
Double check your work,and it is always a good idea to only do one side at a time so you have a comparison to look at if you are winging it without a WIS or diy .You will figure it out and go DOH

 

in the DIY section i printed out in BenzWorld same as the DIY on this forum but pdf file it say i do not have to remove but loosen only the mounting bolts from the back side if im not changing the rotors so i guess i'll just take those mounting bolts off and see whta happen

Thanks ohlord....

 

It's in the engine compartment driver's side wheel well, you'll see brake lines and a module. your vehicle is equipped with asr , it can apply brakes without you hitting a brake pedal so play it safe and key not in the ignition and disconnect the module. Try prying the brake pads a little to colapse the caliper then it should give you enough clearance to lift the caliper off .
If you want a more complete version of this procedure use the search in the w210 section someone did a very nice writeup of it.
