wrong, you can safely mix dot3 and 4, read the labels, only difference is boiling points, not racing dot 3 is fine, new cars use it as proof. don't EVER<EVER mix silicone dot 5 or you will have to flush entire system and refill

For normal street use, Castrol GT LMA Dot 3/4 or Valvoline Synthetic Dot 3/4 should work just fine, mix with all conventional fluids, and are widely available. Won't argue about it with those who think it's the best thing since sliced bread, but I'm not a fan of silicone fluid.

...possibly a caliper leak now...
Thanks to all for the replies. I did most likely 'mix' the two. I had some unopened new DOT4 fluid in the garage. Used it to top off the fluid. I'm still getting 'spungy' type feel and am almost pushing pedal to floor. I had the car looked at prior to purchase, the mechanic said the front left caliper was leaking slightly, but it must be leaking more. I've heard that caliper leaks are common and this style corvette is notorious for them...thoughts anyone one on replacement?

I just replaced my calipers on the 69 vert with calipers from VBP, I ordered the O ring seal type.
The old ones were weeping abit, I didn't notice until the pedal went to the floor backing it out of the garage, and I pulled the wheels and found the backing plates of the pads wet!
I've changed out the flex lines with stainless steel at the same time, along with the master cylinder, now I know the brakes are good.
