Recently Installed a Mc Master cylinder and brake booster on my 84 300D. I bled the brakes how very when I push down the brake pedal it doesn't feel firm but rather spongy. On top of that I got a new brake booster line (The one that connects to to the booster to the pump). However I somehow got a rubber vacuum cap longed in the line on the end that goes in the booster, I can't get it because it's longed to deep.


Do you think because the line loved it would have an effect on the booster working? Thoughts?

Car shuts off fine
No vacuum issues

I tested the vacuum on the line it pulls well above 21
