Technical Details of Sunsong Brake Hydraulic Hose 2201898

This brake hydraulic hose is manufactured using EPDM (ethylene propylene diene monomer) rubber, known for its excellent resistance to heat, ozone, and brake fluid chemicals. The hose length measures 12.91 inches (328 mm), making it suitable for the brake system routing in Audi A4, A4 Quattro, and S4 models. Both ends of the hose have 10 mm female fittings, ensuring compatibility with the vehicle’s brake line connectors. The absence of a bracket means this hose is intended for applications where the original mounting hardware is reused or not required.

Applications and Common Issues Addressed

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 a critical component in the hydraulic braking system of Audi A4 and S4 vehicles. Replacing this hose can resolve several issues:

• Brake fluid leaks due to cracked or worn hoses
• Reduced braking efficiency caused by hose swelling or internal damage
• Brake pedal softness or sponginess from compromised hose integrity
• Corrosion or damage to fittings leading to fluid loss
• Preventative maintenance to avoid brake system failure

Installation Notes and Tips

When installing the Sunsong 2201898 brake hydraulic hose, ensure the vehicle is securely lifted and supported. Carefully remove the old hose, avoiding contamination of the brake fluid system. Use proper tools to disconnect the 10 mm female fittings at both ends. After installation, bleed the brake system thoroughly to remove air and verify there are no leaks. Since this hose does not include a bracket, confirm that the existing mounting hardware is intact and properly secures the hose to prevent movement or abrasion.
