Technical Specifications and Features

This Sunsong brake hydraulic hose (part number 2203121) is constructed from EPDM, a synthetic rubber known for its resistance to heat, ozone, and brake fluid. The hose measures 10.94 inches (278 mm) in length, ensuring proper routing and fitment in the brake system. Both ends of the hose have 10 mm female fittings, providing compatibility with the original brake line connections on the Lexus Land Cruiser, LX450, and Toyota Previa. The absence of a bracket indicates this hose is intended for applications where the existing mounting hardware is reused.

Applications and Problem Resolution

This brake hydraulic hose is used to transfer brake fluid under pressure from the master cylinder to the brake calipers or wheel cylinders. It is essential for maintaining hydraulic pressure and ensuring safe braking operation. This part addresses issues such as:

• Leaking or cracked brake hoses causing fluid loss
• Swollen or deteriorated hoses reducing braking efficiency
• Incorrect hose length or fitting size leading to improper installation
• Brake fluid contamination due to damaged hose material
• Replacement of worn or aged brake hydraulic lines in Lexus and Toyota models

Installation Notes and Tips

When installing the Sunsong brake hydraulic hose 2203121, ensure the vehicle is securely lifted and the brake system is depressurized. Verify that the 10 mm female fittings match the vehicle’s brake line connections. Since this hose does not include a bracket, retain and reuse the original mounting hardware to secure the hose properly. After installation, bleed the brake system thoroughly to remove air and restore proper hydraulic pressure.
