As an automotive enthusiast thanks to my knowledge gained in practice, I can confidently say this product is a waste of money. The brake system is crucial for any performance car, and this so-called "master cylinder" falls short .It's flimsy and doesn't provide the necessary PRESSURE for efficient braking. The only pro is its affordable price, but when it comes to your safety, that should never be the deciding factor. Save yourself the hassle and invest in a higher quality brake master cylinder..
