Cusco Brake Cylinder Stopper 95-98 Nissan Skyline GT-R

This is the Cusco Brake Cylinder Stopper for the 1995-1998 Nissan Skyline GT-R. This part is designed to reduce flex in the brake master cylinder firewall, which can happen under hard braking. By stiffening this area, you get a more solid and consistent pedal feel.

Under heavy braking, the firewall where the master cylinder mounts can flex slightly. This flex means some of the force you apply to the brake pedal is lost before it reaches the master cylinder. The Cusco stopper bolts directly to the firewall and master cylinder, creating a much more rigid connection. This improved rigidity means more of your pedal input is directly translated into hydraulic pressure, giving you a firmer and more responsive brake pedal. It's a popular modification for enthusiasts who want a more direct connection to their braking system.
