Cel P0410 P1411 secondary air

If there is a leak on your brake booster vacuum line, you will feel the braking poor compared to normal....

The leak happens when I move the hose a little. I think that the leak is very minor until you twist the hose a little. I haven't really noticed any difference in braking but I halso haven't driven it all that much since last summer. Just wondering if this leak would trigger the cel codes.

I had a leak on that hose, but the braking wasn't affected. I think there's a check valve along the way that doesn't allow the brake booster to lose vacuum.

I tried driving the car with the hose disconnected while troubleshooting, and it took a tremendous amount of force to push that pedal down, almost impossible to stop the car without that vacuum line. Never thought it would have such an impact.

Did that leak give you any codes?
