Dorman Front Passenger Brake Hydraulic Hose H620442 for Chevy GMC Cadillac – EPDM, Corrosion-Resistant Fittings

Dorman H620442 is a front passenger-side brake hydraulic hose engineered to match the original equipment fit and function for select Chevrolet, GMC and Cadillac trucks and SUVs.

This brake hose is built to replace the factory passenger-side front flexible line on specific model years, restoring the hydraulic connection between the hard line and the caliper. It’s manufactured with EPDM rubber and corrosion-resistant fittings to meet regulated safety and durability standards, and is position-specific to simplify installation. Always verify vehicle fitment by entering your make, model and trim into the garage tool before ordering.

What vehicles will this Dorman hose fit?

The H620442 was designed for numerous Chevrolet, GMC and Cadillac full-size trucks and SUVs from the late 1990s through the mid-2000s. Fitment covers passenger front positions on models such as Silverado, Tahoe, Suburban, Avalanche, Sierra and multiple Escalade/Yukon variants. Check your exact year, trim and bed/cab configuration in the garage tool to confirm compatibility before purchase.

• Cadillac Escalade, Escalade ESV, Escalade EXT (2002–2006 range depending on model)
• Chevrolet Silverado, Avalanche, Tahoe, Suburban (late 1990s–2007 in listed years)
• GMC Sierra, Yukon and Yukon XL (1999–2007 coverage for specified trims)

How does this hose compare to the original part?

Dorman engineers this hose to duplicate the original part’s routing, length and end fittings so braking performance and pedal feel remain consistent after replacement. Materials and fittings are chosen to meet or exceed applicable government durability norms, giving a dependable service life when installed correctly. The hose is position-specific, so it matches the factory geometry for the front passenger side.

• Precision-engineered to mirror original dimensions and fitting types
• EPDM rubber construction for heat and fluid resistance
• Special coating on fittings to resist corrosion and extend service life

What should I know about installation and safety?

Because this is a hydraulic brake component, installation should follow standard brake-service procedures: support the vehicle, depressurize the system, replace the hose, bleed the brakes and inspect for leaks. The position-specific design helps align the hose so it won’t rub or kink when the suspension travels. If you’re not comfortable with brake system work, have a qualified technician perform the installation to maintain safe stopping performance.

• Replace with the vehicle on jack stands and wheels chocked; do not rely on hydraulic jacks alone
• Use new hardware and correct torque values where required; avoid twisting the hose during install
• After installation, fully bleed the brake circuit and check for leaks under pressure

Why choose this Dorman replacement over a generic hose?

This part is manufactured to match the original position and fit, which reduces installation time and the risk of clearance or routing problems common with one-size-fits-all hoses. Dorman tests materials and fittings to meet regulatory durability benchmarks, and the hose includes corrosion-resistant coatings to withstand road conditions. That focus on fit and longevity helps keep brake repairs straightforward and reliable.

• Position-specific design reduces modification or re-routing at installation
• Tested materials and fittings for regulated safety and durability standards
• Cost-effective replacement option that aligns with factory specifications

Who is this for: owners and mechanics restoring braking components on compatible Chevrolet, GMC and Cadillac trucks/SUVs who need a passenger-side front hydraulic hose that reproduces factory fit and function. It’s ideal for brake jobs where a direct-fit replacement reduces installation complexity and helps maintain original braking behavior. Verify vehicle year and trim in the garage tool to ensure this Dorman hose matches your application before ordering.
