Part number 47050-30220 is a brake master cylinder assembly for a Lexus vehicle. This part is responsible for converting the pressure applied to the brake pedal into hydraulic pressure, which then activates the brake calipers to slow down or stop the vehicle. As a used part, it may show signs of wear such as surface scratches, minor rust, or slight discoloration. However, it has been thoroughly tested to ensure it is fully functional and performs as expected. Compatibility with your specific Lexus model should be verified before purchasing.
