When does it fail?
Of the 13 brakes complaints filed for the 2005 Chevrolet Avalanche, here's the actual mileage breakdown — failures cluster heaviest at 150,000+ mi.

Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
What stands out
No new NHTSA brakes complaint has been filed on this vehicle in over 10 years — the issue may be aging out of the active population.
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
The dominant issue across these 13 complaints is catastrophic brake line corrosion. Owners describe brake pedals suddenly sinking to the floor mid-braking, fluid pouring from the front driver side frame area, and complete loss of stopping ability. Multiple owners found the steel lines uncoated and heavily rusted, with ruptures occurring in the bracket holding lines to the frame rail. One owner had all four lines corroded; another had both front lines fail simultaneously.
Troubling: some failures happen early. One owner with a near-pristine 2005 Avalanche at only 14,973 miles needed all brake lines replaced due to severe corrosion. Others hit the problem between 71,000 and 120,000 miles. A single owner of three GM trucks (two Silverados plus this Avalanche) saw identical corrosion failures across all three within eight months.
Secondary issues include premature pad and rotor wear (one report at 71,000 miles), ABS light illumination with service brake messages, and one owner reporting ABS activating unexpectedly during acceleration from a stop. Another noted grinding noise during ABS activation and one report of brake rotor overheating at highway speed.
Owners consistently report that GM declined to acknowledge a design defect, refused assistance, stated no recall existed, and told them to save repair receipts. Owners replaced lines with stainless aftermarket versions.

Failure modes owners describe
Brake line rupture from corrosion
Steel brake lines corrode and rupture, causing complete or near-total loss of brake pressure. Owners report fluid pooling at frame areas, rust visible on uncoated lines, and failure of single or multiple lines (front, rear, or all four).
When: Between 14,973 and 120,000 miles; one owner reported catastrophic failure at low mileage (8-year-old vehicle with only ~15k miles), while others experienced failure at higher mileages. Timing appears independent of age or mileage in some cases.
Symptoms owners cite: Brake pedal sinking to floor with no resistance; Complete loss of brake pressure and stopping ability; Visible rust and corrosion on steel lines; Brake fluid draining from front driver side area; Loss of pressure under hard braking on highway; Vehicle unable to stop; operator forced to use parking brake
Codes mentioned: ABS light illuminated, Service Brake message
Repairs/costs cited: Owners replaced failed lines with stainless steel aftermarket lines or new lines from parts suppliers (NAPA noted as having coating). One owner replaced all four brake lines after corrosion was found in the bracket holding lines to driver side frame rail. Repair costs not specified in narratives.
Recalls/TSBs owners mention: GM refused to acknowledge design flaw or offer assistance in replacing lines. Multiple owners reported GM stating no recall existed and advising them to save receipts for repairs. Owner of three GM vehicles (two Silverados, one Avalanche) reported all three failed with corrosion in same 8-month period; GM response was noncommittal despite clear pattern.
Brake pad and rotor premature wear
Brake pads and discs wear prematurely at relatively low mileage (71,000 miles noted at failure). Cause not identified in narrative; independent mechanic performed repair.
When: At 71,000 miles; owner continued driving to 95,000 miles
Symptoms owners cite: Premature wearing of brake pads and disc
Repairs/costs cited: Repaired by personal mechanic; parts and cost not specified.
ABS malfunction causing wheel lock-up
ABS system activates inappropriately when vehicle attempts to accelerate from a stop, causing loss of power to wheels and preventing movement. Distinct from brake line corrosion failures.
When: At approximately 90,000 miles
Symptoms owners cite: ABS activates during acceleration from stop; Loss of power to wheels; Wheels will not move after ABS activation
Repairs/costs cited: Vehicle not diagnosed or repaired per owner report.
ABS grinding noise during braking
ABS light illuminates when brake pedal is pressed. ABS feature activates just prior to vehicle stopping, producing annoying grinding sound then disengages.
When: <UNKNOWN>
Symptoms owners cite: ABS light comes on when pressing brake pedal; Truck slows normally but ABS activates at end of stop; Grinding noise during ABS activation
Codes mentioned: ABS light
Brake rotor overheating
Brake rotors overheat and produce steam while vehicle is moving at highway speed, resulting in brake failure to engage. Vehicle began decelerating on its own at 70 mph.
When: At 120,000 miles
Symptoms owners cite: Brakes failed to engage; Brake rotors overheated and produced steam; Vehicle began to decelerate on its own
Repairs/costs cited: Vehicle not diagnosed or repaired per owner report.

What owners are reporting 1 most recent
Catastrophic brake failure because of four corroded brake lines. All four lines corroded in the bracket holding the lines to the driver side frame rail. I was driving the vehicle and when I attempted to apply the brakes there was initial resistance and then the brake pedal went straight to the floor. I attempted to apply the brakes again but the vehicle would not stop. I had to apply the parking…

Common questions
How serious is the brakes problem on the 2005 Chevrolet Avalanche?
It's a documented issue but not catastrophic. 13 complaints have been filed. Repairs average $450 and most owners catch it before it causes a breakdown.
At what mileage does the brakes typically fail?
Across the 12 complaints that reported odometer mileage, most brakes failures cluster between 71,000 and 122,072 miles, with the median around 90,000. A quarter of owners report trouble before 71,000; a quarter make it past 122,072. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to brakes?
No active recalls currently cover brakes issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
