1964 brake problems after replacing booster

[61an]

Har bytt booster från birdsnest, efter det trampar jag pedalen i golvet.
Kan det ha med avståndet på pushroden att göra?

I don’t understand the question?

This is not rocket science. Every post on the forum is in English, so use a translator to post your question into English moving forward!

I will use Google translate this time for you and update your Swedish title.

I have changed the booster from birdsnest, after that I step the pedal to the floor.
Could it be related to the distance on the pushrod?

Thanks Biddle! I still don’t quite understand what he’s asking. Is he referring to brake pedal rod or brake booster rod?

Possible that rear seal on master cylinder failed and leaked brake fluid into power booster. Have to replace both once fluid leaks into booster. Contact Bird's Nest and let them help you figure it out

The booster rod setting where it touches the master cylinder has to be perfect. Also, bleeding brakes properly is equally crucial. As mentioned, if the master cylinder leaked into the booster, that would be a serious problem. In addition, I have found that the rusty old brake lines should be replaced on almost all old cars along with the wheel cylinders to be reassured that the brakes are safe.
