i would like to find a diagram for the rear suspension and rear brakes for a 1995 pontiac bonneville

Go to your local public library and ask someone to show you how to access ALLDATA.com . Once you are on the ALLDATA website you will be able to get any and all information on the vehicle.

You can try the autozone site. There is link in the upper left corner, says choose a vehicle, then just follow the directions, go to repair info, then repair guides.

May not be as good as Alldata, but better than nothing.
