Poor brakes

[Mike Baker]

If you can't get the bleeder screws open I would recommend replacing the wheel cylinders at least. I assume that there isn't any brake fluid leaking out anywhere? If not, then there's almost certainly air (or something else which can be compressed) in there. If the brakes hold at all I wouldn't think the master cylinder is bad, but one of the V-Techs on here will know better than I.

I have basically the same problem on my project CDN2 (brake pedal to the floor and nothing happens), and my plan is to replace the entire brake system from the master cylinder through to the drums. It's a tad costly but at least then I'll be sure that the system will work when I need it, and I'll likely never have to replace it again.
