As a new buyer, I installed this professional master cylinder on my performance car and it made a noticeable difference in my automotive braking ability .My analysis of this product showed that it is built with high-quality materials and it fits perfectly with my brake system. The overall performance has been impressive, providing me with more confidence and safety on the road. The only downside is that it IS a bit pricier than other options on the market. Nevertheless I highly recommend it to anyone looking for an excellent brake upgrade option..
