can anyone please tell me the actual size of the fittings on the brake lines, ie the end that goes into the 4 way T [junction box]

my bike is 1994 4x4 2 stroke

 

7/16 inch fitting,IF frozen like a lot of them are a good pair of small vicegrips help!

 

thank you very much, that's what I thought it was [by measurement]

I am having a new rear line made up in Cairns [100 km away] and tech was just asking me the size to be totally sure it was not metric

I had to send him the actual caliper as the fitting was so badly rusted it had to be drilled out, so apparently he has used an "insert" tapped into the caliper

the vicegrips simply sheared the whole fitting off
