I think my brake booster needs to be replaced, but wanted to run it by this group. Brake booster is original I believe.
Have a 70 Challenger with factory front power discs.

- the power brakes work only on the first press - if the brakes are pumped quickly, vacuum is lost and the brakes don't work (they become manual brakes) -- pedal gets harder and harder after each brake press - HUGE difference after 3-4 quick pumps.
- If I wait a bit (5 secs) in between applying the brakes, vacuum builds back up and they're fine.
- seems to be no vacuum leak from intake to check valve.
- couldn't remove the check valve to test it. It's original and I didn't want to break it. But will try again when I have more patience.
- The usual booster test of pumping the brake pedal, holding it, and then starting the engine passes all the time - brake pedal moves downward slightly.
