I have a 2005 C320 Sport that needs new front brake pads. It's a very different setup than I've done before. It looks like two bolts need to be removed to get the outside pad off, then two more to take the inside pad off. I loosened the outside bolts and brake fluid came out. I tried searching the internet about it and came up with nothing, but I know this is a rare car. Is it possible I have to drain the wheel cylinders to take the pads off?
