The Dorman H620052 is a front passenger-side brake hydraulic hose engineered to replicate the original fit and function for select Chevrolet, GMC and Hummer models.

When a brake hose shows age, cracking or leaking, replacing it with a part built to the same measurements and standards as the factory item restores braking reliability and helps complete a safe brake repair. The H620052 is a position-specific hydraulic hose made with EPDM rubber and corrosion-resistant fittings, designed to match the original routing and connection points for the listed model years and trims. Always verify fitment by entering your vehicle details in the garage tool before purchase.

Which vehicles and years does this hose fit?

The H620052 covers a range of Chevrolet and GMC full-size trucks, SUVs and related models from the late 1990s through the mid-2000s, plus Hummer H2. Compatibility is position-specific for the front passenger side, so verifying your make, model and trim is essential.

How does this replacement hose match the original part?

Dorman engineers this hose to mirror the original's length, end fittings, and mounting points so installation and brake line routing remain the same. The materials and coating are selected to meet durability and corrosion-resistance needs similar to OE specifications.

• Exact-position manufacturing for correct routing and clamp locations.
• EPDM rubber compound for flexibility and heat/age resistance.
• Specially coated fittings to reduce corrosion and ensure long service life.

What should I expect during installation and maintenance?

Because the hose is made to original dimensions, installation is typically straightforward for a mechanic or competent DIYer comfortable with brake system work. After installation, the brake system must be properly bled to remove air and inspected for leaks to ensure safe operation.

• Fits existing connections—no custom bending or modifications required.
• Torque fittings to manufacturer specs and use new seals where applicable.
• Bleed the brake system fully and check for leaks before driving.
