Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners of 2006 Chevrolet Avalanches report brake lines corroding and rupturing, causing sudden, complete brake failure at speed. The failures occur across a wide mileage range—from 44,000 miles to 152,000 miles—but consistently involve rust eating through the steel brake lines until they leak or burst. When it happens, the brake pedal goes to the floor with no resistance, and the truck loses all stopping power. One owner had to downshift to stop at 35 mph; another used the parking brake on the highway after foot brakes failed at 55 mph. On-road failures have led to near-collisions and at least one actual crash.
The corrosion is aggressive enough that one owner noted the lines rusted through in just ten years of ownership, which he considered premature for a safety-critical component. Multiple owners cite this as a known issue across model years. GM supplies a brake line kit that requires replacement of all metal brake lines, front and rear. One owner reported the manufacturer covered repair costs, though the truck was not actually repaired before the claim was reported. Repair shops cite corrosion as the root cause and say the lines are too weak to patch.

Failure modes owners describe
Brake line corrosion and rupture
Steel brake lines develop rust and corrode through, creating holes or ruptures that cause complete or partial brake fluid loss and brake failure. Owners report lines rusting through as early as 10 years of ownership.
When: 44,000 to 152,000 miles; at least one failure occurred around 10 years of vehicle ownership
Symptoms owners cite: Brake pedal goes to floor with no resistance; Loss of all braking power; Brake lines visible corrosion and perforation; Pedal may feel soft before failure
Repairs/costs cited: Brake line replacement required. GM offers a brake line kit for complete front and rear metal brake line replacement. One owner reported manufacturer agreed to cover repair costs.
Recalls/TSBs owners mention: GM has a brake line replacement kit available; at least one owner reported GM covered repair costs under warranty consideration.
Brake system loss of redundancy
When brake line fails, the system appears to lose any redundant braking capability. Owners report losing ability to stop the vehicle with foot brake alone; parking brake becomes the only stopping method.
When: On-demand during highway or urban driving
Symptoms owners cite: Complete loss of foot brake function; Parking brake becomes only functional stopping method; Brake pedal to floor with no stopping power

Brakes failed coming to traffic light. Pedal went to floor. Went half way thru before truck stopped. Inspected and found rear brake steel line had rusted thru and had a hole. Brakes should not rust thru in only ten years,
Suddenly and without any warning the brakes failed while attempting to stop for traffic on the highway. The brake pedal went to the floor and it appeared that all braking had been lost. The car was navigated to the shoulder and the parking brake was used to come to a full stop. If the brake pedal was engaged and the parking brake released, the car would begin to move again. This appeared to…
Brake lines rusted out. Apparently this is an issue for this year and many other model year vehicles. Considering the brakes stop the vehicle, this is a big safety issue, and very expensive to be fixed.
