corroded Rear Brake pipes
 

My '97 wrx import has failed the M.O.T. for the rear pipes rotting so I'm replacing them with stainless braided hose.

but I don't know what size fitting is on the end of the flexi hose on the caliper (size and pitch of thread), I will need to buy a male to male adapter but without stripping them down and taking the caliper to the shop I have no idea.

Can anyone shed some light on this?:wonder:
