Front PASSENGER side hose. Order the matching driver side (Dorman H620779) for a complete front-axle hose refresh. Full brake hoses collection.

Why Replace Both Front Hoses Together

• Both hoses age at the same rate — if one has failed, the other is close behind
• Even braking — a fresh hose on one side and a ballooning hose on the other gives uneven brake force
• You are already bleeding the system — do both while the brakes are open
• EPDM rubber and coated fittings — resists the corrosion that kills factory hoses in salt-belt states

Install Notes

• Use a flare-nut wrench on the hard-line fitting to avoid rounding the soft brass fitting
• Replace the copper crush washers on the banjo bolt — never reuse old washers
• Bleed the front brakes after install — passenger side first, then driver side
• Verify no hose contact with the tire or suspension at full steering lock
• Torque banjo bolt to GM service spec — do not overtighten
