GKTech Nissan R32 GTS-T/GT-R Skyline Brake Master Cylinder Stopper

The GKTech Brake Master Cylinder Stopper is a simple but highly effective way to improve brake pedal feel and consistency in your R32 GTS-T or GT-R Skyline. Under hard braking, the factory sheet metal firewall can flex, allowing the brake master cylinder to move slightly—resulting in a soft or inconsistent pedal. This stopper reinforces the master cylinder, minimizing flex and translating more of your pedal input directly to the brakes.

Designed specifically for right-hand drive R32 Skylines, this bracket bolts directly to the strut tower and adjusts to brace against the master cylinder body. It’s a lightweight, bolt-on upgrade that offers noticeably firmer, more responsive braking—perfect for street and track use.
