A Guide to Replacing Brake Pads on Your 2005-2019 Buick LaCrosse
Everything LaCrosse owners need to know about choosing the right aftermarket brake pads for safe, quiet stopping.
- For most LaCrosse owners, ceramic brake pads from a premium aftermarket brand like ACDelco Gold, Akebono, or Bosch offer the best balance of quiet performance, low dust, and value.
- Always replace brake hardware with the pads and inspect the rotors for wear; replace them if they are grooved, vibrating, or below the minimum thickness.
- Owners of 2017-2019 models should be aware of the Electronic Parking Brake (EPB), which requires a scan tool for rear brake service.
- Check for open recalls, especially for 2005, 2014, and 2018-2019 models, which had brake-related safety campaigns.
Signs of Worn Brake Pads
Your LaCrosse will give you several warning signs when the brake pads are nearing the end of their life. Ignoring these can lead to more extensive and costly repairs. Common signs include:
- Squealing or Screeching: A high-pitched noise when you apply the brakes is often the first sign. This is caused by a small metal tab called a wear indicator, which is designed to make noise when the pads are thin.
- Grinding Noises: A loud, harsh grinding sound means the brake pads have worn down completely. This is metal-on-metal contact between the pad's backing plate and the rotor, which can quickly cause damage and reduce stopping ability.
- Vibrating Brake Pedal: A pulsating or vibrating feeling in the brake pedal or steering wheel when braking can indicate unevenly worn pads or warped rotors.
- Longer Stopping Distances: If you notice your car takes longer to stop than it used to, your brake pads may be too worn to create effective friction.
Choosing the Right Aftermarket Brake Pads
The original pads on your LaCrosse are a good benchmark, but many aftermarket options offer similar or even better performance, often at a lower price. The main choice you'll make is between ceramic and semi-metallic pads.
- Ceramic Pads: These are the most popular choice for daily drivers. They are known for being very quiet and producing very little brake dust, which keeps your wheels cleaner. They offer smooth, consistent stopping power for normal driving. For most LaCrosse owners, ceramic pads are the best choice.
- Semi-Metallic Pads: These pads contain metal fibers and offer excellent performance, especially under high heat and heavy braking. They can be slightly noisier and produce more dust than ceramic pads. They are a good option for those who drive aggressively or live in hilly areas.
Brand Tiers for Your LaCrosse
Here's a breakdown of popular aftermarket brands to help you choose:
- OEM-Equivalent / Premium: Brands like ACDelco Gold (Professional), Akebono, Bosch, and Brembo offer pads designed to meet or exceed the quality of the original factory parts. ACDelco is the original parts supplier for GM, and their Gold line is a high-quality choice. Akebono is also a known OEM supplier for many brands, including GM, and is praised for quiet operation and low dust.
- Quality Daily-Driver: Brands such as Wagner, Raybestos, and Powerstop (Z17/Z16) provide a great balance of performance, low noise, and value. They often feature advanced shim technology for quiet operation and are available in both ceramic and semi-metallic formulas.
- Economy / Value: Brands like Pronto, Dynamic Friction, Total Stopping Solutions, and ACDelco Silver (Advantage) offer a budget-friendly solution. These pads provide safe, reliable braking for everyday use and are a good option if cost is the primary concern.
Pro-Tip: Always replace brake hardware, like clips and springs, when you replace your pads. Many quality brake pad sets include new hardware in the box. This ensures the pads move freely and helps prevent noise and uneven wear.
Generation and Model Specifics
The 2005-2019 LaCrosse spans three generations, and brake systems can vary. It's crucial to get the right parts for your specific year and trim.
- First Generation (2005-2009): These models use a straightforward brake setup. Replacement is a common DIY job. 🎬 Watch this step-by-step DIY brake pad replacement for 2005-2009 models.
- Second Generation (2010-2016): Similar to the first generation, but always verify part numbers as different brake packages may have been available. 🎬 Learn how to replace front brake pads and rotors on 2010-2016 models.
- Third Generation (2017-2019): Later models may feature an Electronic Parking Brake (EPB). Replacing rear brake pads on cars with an EPB requires a special scan tool to put the brakes into service mode. Attempting to compress the caliper piston without doing this can damage the caliper. Also, be aware of different rotor sizes based on wheel size (e.g., 17-inch wheels).
Known Issues, Recalls, and TSBs
While there are no recalls specifically for brake pad failure across all years, a few related items are worth noting:
- 2005 Recall (NHTSA #05V156000): On some early models, a clip securing the brake pushrod to the brake pedal could detach, potentially causing a complete loss of brakes.
- 2014 Recall (NHTSA #14V234000): A small number of 2014 models were recalled because thinner rear brake rotors may have been installed on the front by mistake. This could cause a brake pad to detach from the caliper.
- 2018-2019 Recall (NHTSA #18V586000): Some vehicles were recalled for rear brake caliper pistons with an insufficient coating, which could lead to gas pockets forming and reduced rear brake performance. The fix involves bleeding the brake system.
Aftermarket vs. OEM Brake Pads
Original Equipment (OEM) brake pads for your LaCrosse are made by ACDelco. They are designed to provide a quiet, smooth stop with low dust, which is why most are ceramic. High-quality aftermarket brands like Akebono, Bosch, and Wagner often use similar ceramic formulations and can provide the same or better performance for less money. Economy brands will stop the car safely but may not last as long or be as quiet as premium ceramic options. For most owners, a premium aftermarket ceramic pad offers the best combination of quality, performance, and value.

Frequently Asked Questions (FAQ)
Do I have to replace my rotors with my pads?
It is not always required, but it is highly recommended. New pads perform best on a fresh, flat rotor surface. If your current rotors are vibrating, heavily grooved, or below the minimum thickness stamped on the rotor itself, they must be replaced for safety.
What's the difference between front and rear brake pads?
Front and rear brake pads are not interchangeable. The front brakes do most of the stopping work, so the pads are typically larger than the rear pads. Always ensure you are ordering the correct pads for the front or rear axle.
How often should I replace my LaCrosse's brake pads?
Brake pad life varies greatly depending on the pad material, your driving style, and conditions (city vs. highway). A general estimate is every 30,000 to 70,000 miles. The best approach is to have them inspected annually and replace them when you hear the wear indicator squeal or when a mechanic measures them as being near their service limit.
What is 'bedding in' new brake pads?
Bedding-in is a process of several controlled stops after installation. It transfers a thin, even layer of friction material from the new pads onto the rotors. This process ensures smooth, quiet, and powerful braking performance right from the start. Most manufacturers provide specific instructions on the box.
