The Brake Master Cylinder on your vehicle is constantly working, and unfortunately can wear out and start to leak over time. This creates a mushy-spongy brake pedal feeling that often results in an unsafe brake condition because the pedal may sink to the floor when depressed. Mando OE Brake Master Cylinders helps combat this very issue, and bring back the original brake pedal function. Produced in IS/TS certified facilities, Mando meets all the strict requirements to meet factory safety standards of your Hyundai & Kia. Mando – We Are OE!
