Front brake Problems

[Candygold16]

After fitting new brake shoes on my front brake (which wasn't operating brilliantly before) My front brake seems to be really bad is this because the front brake on a 1974 fs1e is just bad or is this because the brake shoes need bedding in ? The brake is fully adjusted properly but when applied you can still just about push the bike along ! I think my problem might be lying with my brake arm. When i purchased the bike i noticed that a relatively new brake arm has been fitted to the bike ?? What is the correct length for a 1974 fs1e brake arm ??
It would be great to sort this problem !
Thanks

You may have pushed the arm over the splines to far ease it back a bit and try squirting some 3 in 1 oil down the cable from the handle bar end and just keep trying it, they are a pain but when they work they do very well...
