Durable Construction and Precise Fitment

This Dorman brake hydraulic hose (part number H381342) is built with EPDM rubber, known for its resistance to heat, ozone, and brake fluid degradation. The black rubber outer sleeve adds an extra layer of protection against abrasion and environmental factors. Both ends of the hose are equipped with treated steel fittings—one banjo fitting with a 10 mm thread diameter and one female fitting with a 7/16 in-24 inside diameter—ensuring a secure connection to your vehicle's brake system. The included gaskets help maintain a tight seal, preventing leaks and maintaining brake system integrity.

Compatible Vehicles and Applications

This brake hydraulic hose is specifically designed for use with the following vehicles:

  • Chevrolet Blazer
  • GMC Jimmy
  • Chevrolet S10
  • GMC Sonoma

It is ideal for replacing worn or damaged brake hoses that can cause brake fluid leaks, reduced braking efficiency, or spongy brake pedal feel.

Common Issues Addressed by This Brake Hose

  • Brake fluid leaks due to cracked or deteriorated hoses
  • Reduced brake responsiveness caused by hose swelling or internal damage
  • Brake pedal softness or sponginess from compromised hydraulic lines
  • Corrosion or damage to fittings leading to fluid loss
  • Wear from abrasion or environmental exposure

Installation Notes and Tips

Installation of the Dorman H381342 brake hydraulic hose requires basic mechanical skills and proper tools. Ensure the vehicle is securely lifted and supported before beginning. When removing the old hose, take care to avoid contaminating the brake system with dirt or debris. Replace the gaskets included with the new hose to ensure a leak-free seal. After installation, bleed the brake system thoroughly to remove any air and restore proper brake function.
