# Master Cylinder - URL: https://www.gt2i.com/en/180/master-cylinder ## Description The brake master cylinder plays a crucial role in your sports car's braking system. Got a race coming up? You need brakes that are reliable and effective to achieve the best results. Under hydraulic pressure, the master cylinder transmits brake fluid to the entire brake circuit. If this part malfunctions, you will not be able to brake. Below, we explain how it works and how to plan for its replacement. GT2i offers a wide range of brake master cylinders suitable for all configurations: single or double circuit, with or without integrated reservoir, different strokes and diameters to suit every type of vehicle or use. Each model is designed with high-quality materials, such as forged aluminum or treated steel, to ensure lightness, strength, and heat resistance. The GT2i brake master cylinder guarantees a quick reaction to the pedal, smooth pressure modulation, and precise feedback for better braking control. It is compatible with pedal supports, distributors and accessories offered by GT2i, ensuring simple and efficient installation. Trust GT2i, the motorsport expert, to provide you with a reliable, durable and high-performance brake master cylinder. Enjoy optimized braking for every critical stop, every tight corner and every intense braking straight. ## Subcategories - [Master Cylinder - With Reservoir](https://www.gt2i.com/en/182/master-cylinder-with-reservoir) -
