After trying this product on my performance car, I am blown away by the immediate difference in stopping power .The hydraulic system is top-notch and responds quickly to my foot on the brake pedal. As an automotive enthusiast, i appreciate THE professional grade quality of this product. While the cost is slightly higher than some other brake system products, the increased safety and performance make it worth the investment. Overall I highly recommend Raybestos Hydraulic for anyone looking to upgrade their brake system..
