1. Precision OE Fitment

• OEM Part Number: 89544-0D050

• Engineered in strict accordance with OE tolerances, mounting hole locations, bearing dimensions, and flange geometry. Precision-aligned mounting holes and spline configuration ensure a perfect fit with the steering knuckle and brake disc, providing quick and convenient installation, smooth rotation, and accurate alignment.

2. High-Precision Ball/Roller Bearing for Smooth & Quiet Operation

• Built with high-precision ball or roller bearing components and optimized raceway geometry for excellent load capacity and low rolling resistance. Effectively reduces rotational friction, wheel-end noise, and vibration, delivering a smoother, quieter, and more comfortable driving experience.

3. High-Strength Alloy Steel & Multi-Layer Sealing for Long-Lasting Durability

• Constructed from high-strength forged alloy steel with precision heat treatment for excellent shear strength and wear resistance. Advanced dust- and water-resistant seals combined with long-lasting high-temperature grease effectively protect against dirt, moisture, and road contaminants, ensuring extended service life and reliable driving safety.

4. Made in Taiwan (MIT) Quality Assurance

• Built with high-standard manufacturing processes and rigorous quality management. Each brake master cylinder assembly undergoes 100% strict testing prior to factory shipment to ensure zero-defect quality.
