[Spridgets] brakes

[lindalnhvt at nhvt.net]

I just spent quite a while jacking up various wheels and bleeding the
brakes of my Sprite. Used an EZ bleed and cleared some air and old fluid.
I had good brake pedal pressure for about 30 seconds and now have
practically nothing.  I can get a little braking if I pump a few times,
but it's dangerous at best..
I paid a shop to install a new slave cylinder last year and the system
hasn't been the same since.  At first the gears were grinding and I had
them fix it.
Do I now need to bleed the slave cylinder?  If so, what's the easiest
method to get at it.
Thanks.
