Raybestos MC391303 Professional Master Cylinder Review

This master cylinder is a real letdown for automotive enthusiasts looking to upgrade their brake system .Using this product, our team found that the overall performance was lackluster and provided no noticeable improvement to our vehicle's braking abilities. The one advantage was that installation was relatively easy but that's not enough to justify the hefty price tag. Don't waste your hard-earned cash on this underwhelming product..

Based on my experience installing this professional-grade master cylinder, it is a significant upgrade from OEM.The improved pedal feel and response provide confidence when driving aggressively. The high-quality construction and precision machining ensure longevity and resistance to wear over time. However, the heavier weight may be a concern for some drivers looking for a lightweight option. Overall, an excellent choice for those seeking performance and reliability..

A few hours later I got a call from the auto repair shop and was told that the master cylinder inner seal had ruptured which in turn caused the brake booster to fail due to hydraulic fluid getting into the brake booster, fouling it and causing the car to stall out of service. A simple exchange cost me $620 due to damage and labor and no car for 5 days due to having to ship 2 new parts to Alaska. I have tried to get a refund from
