This GKTech brake line kit is the hard line delete version and so replaces your OEM hard lines at the front and rear calipers so you have just the one braided line going to them.
The GKTECH braided brake lines are a direct replacement of the factory lines and are stronger (read: more reliable) than the factory rubber lines which are prone to breaking but they also eliminate the spongy feel of the standard brake lines.
The front lines are also longer to compensate for big brake setups or cars with more steering lock (which would see stretching with the factory line).
The brake lines are manufactured specifically for GKTECH and they comply with all DOT, TUV, and ADR specifications.
These lines with Brembo Calipers:
If you are upgrading to the Brembo calipers released on Nissans (R33 GTR, R34 GTR and Z33/Z34's) all use the same thread and fitting type as standard Nissan items so these lines will suit. If you're running (or planning on) running different calipers, check that the standard fitting is the same as the new calipers fitting. FYI standard Nissan calipers are all M10x1.0
