My old brake lines from the banjo bolt fitting to the metal brake line at my front calipers are being replaced and I ran into this problem.
At the banjo end the threading is M10-1.0 male while the end of my new line is a M10-1.0 female.
The brakes are a four piston design so I'm assuming it's a Toyota upgrade. The new brake line is a Centric 150.42010 from Rock Auto.
Did the Toyota caliper take a different flexible brake line than the stock 260z brake caliper?
thanks
