Detailed Description

The brake master cylinder is a critical hydraulic component that converts pedal force into brake pressure. When the internal seals wear or the unit begins to leak, the pedal can feel spongy, travel too far, or sink under pressure. Mando 17A1128 is an OE replacement built to match factory requirements for compatible Hyundai and Kia brake systems, including 2002-2005 Hyundai Sonata without traction control, 2003 Kia Optima from 09/30/2002, 2004-2005 Kia Optima with OE rack and pinion assembly with ABS wheel speed sensor and disc brake caliper, and 2006 Kia Optima older generation.

If you are servicing a Hyundai Sonata brake master cylinder or replacing a Kia Optima master cylinder, this part number 17A1128 provides a direct OE-style solution for the listed applications.

This part cross-references Hyundai and Kia OE numbers 58510-3D500 and 585103D500 for the same application.

What It Helps Address

• Soft or spongy brake pedal feel
• Brake pedal travel that increases over time
• Brake fluid leakage at the master cylinder
• Pedal sinking when pressure is applied
• Loss of consistent hydraulic brake response

Installation Notes and Tips

Confirm vehicle year, make, model, and configuration before ordering, since fitment varies by traction control and ABS-related notes. After installation, the brake hydraulic system should be properly bled to remove air and restore pedal firmness. Inspect brake lines, fluid condition, and related hydraulic components during service to help verify the repair.
