changing out flex hoses

Hi All,

I just did a brake job on my '72 280SEL 4.5. Everything went fine, the brakes work great. But I was unable to replace the existing front flex hoses because I couldn't loosen the fittings! I tried all the obvious solutions, such as using penetrant, and then applying heat, etc. Even a sharp strike or two with a copper mallet, but no luck. (I haven't tried freezing and then heating.) Does anyone have some tips for loosening those fittings?

Thanks very much,

Cut the hose, put a socket on the remaining end of the flexible line, firmly clamp the hard line and remove the female fitting. Heat can be a great assistance if the fittings are really stuck.

sometime a sharp wise grip on the 11mm part will do the trick .
