Loctite/copper washer/other?

Local trials specialist fitted a new clutch & clutch hose as part of diagnosing killer drag issues.

Today's the second time I've taken the bike out...

.. and suddenly no clutch. The fluid running down the hose reveals the brake line has worked itself loose. FFS.

Should the union have a copper washer, loctite, PTFE, fernox or something else to stop this happening?

Alloy or Copper washer would be ok. But you should inspect the mating surfaces for scratches and dents. And also inspect for cracks because if correctly assembled this would rarely happen.

Isn't the purpose of a crush washer to account for scratches and dents?

 

I've not seen a bike assembled without crush washers before, is it a new thing to not need them?

I would ask him where that formula master cylinder came from. WE were throwing those in the trash not long ago.

It was already on the bike?

 

A new clutch and hose were fitted, not the master cylinder.
