Under the bolsters there should be a few small grommets. Instead of each grommet is a small screw, loosen all the screws and lift the coming pads straight up. There are small brackets that hold each one in position when they are re-installed.
When you get the coming pads of the brackets they hang on might be rusted through. I replace my 2004 pads and the brackets were flaking apart they were so rusted. Grady dealer had them in stock - Good luck
