I've got her to run, but need her to stop.

[Blaze69]

Hi all,
Been awhile since I last posted, anyway here's my problem.
As I posted a while ago I was in the process of changing over to front disc on my '69. It took me a bit but I finally got it finished (somewhat). Here's what I've done so far:

1: swapped out the front end (that's a given), replaced the discs, pads, hoses, calipers and bearings.
2: bought new drums for the rear.
3. made new hoses (lines) to match the new setup.
4. Bled the **** out of the system, I now have clear fluid running to all the wheels.


What I didn't change was the booster or master cylinder.

My problem now is that when I got to stop I don't have any brakes on the first attempt. But, if I lightly pump the pedal the vehicle will damn near lock up.

I hope that someone out there can give me some advice on this matter. I would sure hate to have to take it into the shop and pay someone else for something I should fix.

Thanks.
