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.
This Preliminary Information communication provides the technician with the additional steps that are needed to help perform a successful brake bleed on the 2-Mode Hybrid with Regular Production Option Code HP2. With a battery maintainer installed on the vehicle use brake pressure bleeder that maintains 30 psi for the entire bleed procedure.

The failure pattern owners describe
Brake failures in this 2011 Silverado cluster run from simple to serious. Rear wheel cylinders leak heavily, contaminating brake shoes and causing chatter—happening by 35k miles on regularly serviced trucks. Brake shoes also stick to drums after wet weather, requiring hard throttle to break free.
The critical stuff: owners report brake pedal unresponsiveness at speed. At 60 mph, stepping the pedal hard does nothing; the truck keeps rolling and owners have to mash the pedal or steer out of traffic to avoid hitting other vehicles. Some incidents involved collisions. One brake failure on I-26 involved fluid leaking from a corroded front line at under 59k miles.
ABS and traction control systems malfunction regularly. Below 25°F, warning lights flood the dash and the anti-lock function quits—the truck rear-ends slide on snow with power steering to the least-grip wheel. At higher mileage (76k) brakes seize entirely. Rear drum brakes produce excessive dust and squeak from 16k miles onward. Dealers clean them twice, it comes back. Pulsating pedals persist even after pad and rotor service.
One owner's stability lights stay on after sensor replacement, killing the ABS and creating an unsafe tow vehicle. Dealers often cannot diagnose the electronic issues; manufacturer assistance is sparse.

Failure modes owners describe
Rear wheel cylinder leakage and brake chatter
Left rear wheel cylinder leaked heavily with contaminated brake shoes; right rear cylinder seeping. Owners report chattering noise from rear brakes.
When: 35,574 miles; October 2014
Symptoms owners cite: Chattering noise from rear brakes when pedal applied; Brake fluid leakage at rear wheels
Repairs/costs cited: Replaced rear wheel cylinders, brake shoes; resurfaced drums; bled system. Cost $514.74 out-of-pocket after $15 reward card credit.
Recalls/TSBs owners mention: Service manager indicated GM would process a partial refund via check within two weeks.
Brake pedal unresponsive at speed
Vehicle failed to slow down when brake pedal depressed at highway speeds (55-60 mph or 60 mph). Owners applied extreme pressure to stop vehicle; some incidents involved collisions with other vehicles.
When: 7,000–114 miles for initial occurrences; 55–59k miles for high-speed failure incident
Symptoms owners cite: Brake pedal depressed but vehicle continued moving or slowed inadequately; Tire squeal followed by firm pedal but no braking effect; Required extreme pedal pressure to bring vehicle to stop; Brakes functioned normally after incident
Repairs/costs cited: Dealer inspection found nothing wrong; advised computer should stop vehicle. No repair performed. One incident involved brake fluid leak at left front (corrosion present); leak location unclear (rubber hose or metal tubing).
Recalls/TSBs owners mention: Manufacturer notified; offered no assistance in some cases.
ABS and traction control malfunction in cold weather
Dashboard warning messages for traction control and ABS failure appear exclusively in temperatures below 25°F. On snow-covered roads, vehicle rear axle sent power to wheel with least traction, causing rear-end sliding. ABS brakes did not function as anti-lock. Owner reports this issue occurs across multiple GM brand vehicles.
When: Cold weather conditions only; temperatures below 25°F
Symptoms owners cite: Traction control and ABS warning messages on dashboard in cold weather; Vehicle rear end slides on snow-covered road; ABS brakes fail to lock; power goes to wheel with least traction; Difficulty shifting out of park preceding failure
Rear brake shoe adhesion after wet conditions
Rear brake shoes stick to drums after exposure to moisture when parking brake applied. Shoes release abruptly when vehicle shifted into Drive or Reverse, causing vehicle to resist movement until accelerator depressed. Braking feel differs between wet and dry conditions.
When: After wet weather or washing
Symptoms owners cite: Rear brake shoes stick to drums when parking brake applied after wet conditions; Thudding noise when vehicle shifted into Drive or Reverse; Vehicle will not move until accelerator depressed; Braking feel different in wet vs. dry conditions
ABS spontaneous activation while driving
Anti-lock brake system activates independently at speeds 20 mph and above, causing unwanted vehicle deceleration without driver input.
When: Very low mileage (approximately 6 miles)
Symptoms owners cite: ABS activates independently while driving 20 mph or above; Vehicle decelerates without brake pedal input
Recalls/TSBs owners mention: Dealer unable to diagnose or duplicate failure; manufacturer offered no assistance.
Brake pulsation unresolved by service
Pulsating sensation felt when brake pedal depressed. Dealer replaced brake pads and resurfaced rotors and drums, but pulsation persisted.
When: Very low mileage (approximately 114 miles)
Symptoms owners cite: Pulsating sensation when depressing brake pedal
Repairs/costs cited: Pads replaced; rotors and drums resurfaced. Pulsation continued after repair.
Recalls/TSBs owners mention: Manufacturer offered no assistance.
Rear drum brake squeaking with excessive dust
Rear drum brakes squeaked continuously starting at 16,000 miles. Dealer cleaned brakes twice; each cleaning revealed excessive brake dust. Problem resolved temporarily but returned repeatedly.
When: Starting at 16,000 miles; recurred multiple times
Symptoms owners cite: Rear brake squeaking noise; Excessive brake dust present
Repairs/costs cited: Dealer cleaned rear drum brakes twice; temporary resolution only.
Brake failure due to longer stopping distance
Vehicle took longer than usual to stop when brake pedal depressed at normal speeds, making vehicle unsafe to operate.
When: 62,765 miles
Symptoms owners cite: Engine knocking noise and traction warning light illuminated; Longer stopping time than normal; Burned spark plugs (number 1 and 7) diagnosed
Repairs/costs cited: Spark plugs replaced; failure recurred.
Recalls/TSBs owners mention: Manufacturer notified and opened case reference 8/2905223479.
Seized rear brakes
Rear brakes seized while driving, immobilizing vehicle.
When: 76,000 miles
Symptoms owners cite: Brakes seized
Recalls/TSBs owners mention: Manufacturer referred owner to NHTSA Hotline; no repair performed.
Stability and ABS warning lights—recurring activation
StabiliTrak, anti-skid, and ABS warning lights illuminate intermittently, disabling anti-lock brakes. After sensor replacement, warnings continue to appear randomly regardless of vehicle load. Owner reports unsafe condition, especially when towing horse trailer.
When: Recurring within one-month period; initially at unspecified mileage
Symptoms owners cite: StabiliTrak, anti-skid, and ABS warning lights activate randomly; Anti-lock brakes disabled when warnings active; Warnings appear with no load in or on truck; Did not occur while hauling
Repairs/costs cited: Rear differential signal sensor replaced; warnings persist.
