Cb550 front brake
hairygit:
If the hoses are more than a few years old (black rubber type) they can get weak and expand under pressure and give the symptoms of a spongy lever even if there is no air in the system. The only way to find out is to renew the hoses, if you're not bothered about originality use braided stainless covered ones, they have far greater resistance to expansion, and are a useful upgrade.

Thanks is this a common problem?
Is there any things I might need to check?

Rubber brake hoses SHOULD be changed every 3 years for safety reasons, a lot of people wait until they start to crack with age or fail the M.O.T. for it, They are cheap to replace, and make an incredible difference to the braking, which is never a bad thing on a bike!

Believe it or not, mine are on since 1976 and show no cracks.

I believe you, if they are protected from direct sunlight, they don't suffer as much from cracking caused by U.V. degradation, but if you fitted new hoses you would certainly notice a difference!
