could be a bad seal on one of the camshafts. could also be from the valve cover. You need to wash the engine down carefully -don't get the wires wet and look closely for the oil path. is it engine oil or transmission fluid?

jack the car up saftely then take the wheels off .. then you will see the brake calipier turn the wheel towards you so the calipier is facing you . at the bottom of the calp you will see a small bolt at bottom undo this and lift prize the calp up then remove 1 pad the inside on where the piston is then put calp back down and put the bolt back in just to hold it in place then when you have done this put a large stronge screw driver in via hole in front to push the piston all the way back but make sure you do the evenly and piston goes in straight or it will get stuck same with all types of brakes. once you have done this reopen calp and take the other pad out clean all area with a wire brush and replace the new pads in place,, and retighten bolt etc , before you start the other side please make sure you pump brake peddle until it goes hard again. then do same to over side ,

hope this is a great help matdav69
