Hello and thank you for letting me join.

I have a 1991 940 turbo volvo and i'm trying to replace my rear brake pads and rotors but I need to know if I have multi link suspension or not?? Your input is very much appreciated. Thank you

 

You have a live axle. The independent rear suspension (also known as multilink) with axles and cv joints was used in the later 960's- S90's.

But to be sure look under the car for a live axle rear end -

If you are looking for brake pads - your car uses the same ones as a 240, and many other Volvos - and these are the rotors (same as 240/740 also)
