Currently fitting a brake line kit from mini spares and I thought it came with a line from the clutch master to the bulkhead mounting point for the flexi hose. The kit has come with 3 different length hoses all labled up as 'master cylinder to valve'. Being its for a tandem yellow lable brake master (the 2 fit fine into brake master) I assumed the 3rd spare line was for the clutch, but the thread will not take. There is no damage to either thread.
Incidently it also does not fit into the new clutch flexi hose that I have just fitted, which makes me think the clutch line threads are slightly different.

I would speak to minspares but or course its bank holiday and I need to know as I won't sleep tonight!

Can anyone clear this up for me. cheers

Yellow band master is M10x1 top & M12x1 bottom. The clutch master should be 3/8unf. that's slightly smaller than m10x1, so imperial in metric is a loose fit and the other way round you risk damaging the thread if you force it.

 

Part number?

Ok, guessing by the description, there's an extra pipe included 12x1 for the yellow band as well as one for a black band cylinder.
