Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

Time to remove failed classic ABS components.


Brake fluid absorbs the moisture and turns it into chemical substance to protect the internal wall of brake hard line, master cyl, caliper, piston, etc but not the external fitting.















Many of the brake pipe fittings were seized on this NSX but this one at the master cyl just didn't want moving.

Even after using the ATF/Acetone + crowfoot, still no movement.
Could have cut the pipe and use 6 point socket but as not going to replace the master cyl on this occasion, didn't want emptying the reservoir (no bench bleeding) so used the final resort method of my trusted Knipex tool.
With massive torque applied, finally it came loose.
