fitting size for master cylinder ?
Hey guys,
removed my booster and master cylinder today to fit new ones, but snapped one of the little pipes that go from the master cylinder to the prop valve, the nut cracked off but just wouldnt let go of the pipe itself and twisted it so i thought the hell with this, with it being such a small pipe i can replace it.
I just dont know what size male fitting is needed for each end ? this is the rear pipe closest to the brake booster
