Detailed Description

Dorman H620357 is a brake hydraulic hose built to replace the original hose on specific vehicle applications where a flexible hydraulic connection is required between hard brake lines and moving suspension or steering components. The hose uses EPDM rubber for fluid resistance and flexibility, while the treated steel fittings and stamped steel bracket help maintain a secure, factory-style installation. This part cross-references Raybestos Brakes BH381322 for the same application.

Use H620357 when servicing brake systems on Chevrolet Silverado and GMC Sierra models that require the correct hose length, fitting style, and bracket configuration. The design supports a clean replacement during brake line repair and helps restore proper hydraulic routing at the wheel end.

What It Helps Fix

• Cracked or deteriorated brake hose rubber
• Brake fluid seepage at hose fittings
• Restricted brake fluid flow from internal hose wear
• Corrosion or damage at the hose bracket area
• Brake line routing issues after suspension or brake service

Installation Notes and Tips

Replace the hose as part of a complete brake repair and inspect adjacent hard lines, calipers, and mounting points before installation. Confirm the male and female thread sizes, bracket location, and hose length match the original setup before tightening the connections. Bleed the brake system after installation to remove air and restore pedal feel.
