Review on Dorman M630808 Brake Master Cylinder by Tim Martin

As a result of my tests I determined that this brake master cylinder is a complete waste of money. Despite being advertised as a high-performance option, it failed to deliver even basic braking functionality. The only redeeming quality is its affordable price, but even then, it's not worth it considering the safety risks. Avoid this product at all costs if you care about your car's performance and your own safety..
