Signs Your Brake Hose Needs Replacement

• Surface cracks or dry rot in the rubber — replace immediately
• Swelling or ballooning under braking — internal delamination, spongy pedal
• Brake fluid weeping at the fittings or along the hose
• One brake dragging — a collapsed hose acts as a check valve, holding pressure on one caliper
• Age — original hoses start failing around 10-15 years regardless of mileage

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
