A Guide to Replacing Disc Brake Calipers on the 2011-2017 Buick Regal
Address common sticking, pulling, and leaking brake issues on your Buick Regal with the right replacement caliper.
- You must correctly identify if your Regal has standard calipers or the larger Brembo calipers found on the GS model before ordering parts.
- Replacing the rear calipers requires a special tool to retract the piston; failure to use this tool will result in damage.
- Sticking or seized calipers are a known problem; symptoms include a shaking steering wheel and a hot, burning smell from the wheels.
- For 2011-2012 models, check TSB PIC5692A, as a sticking brake pedal can mimic the symptoms of a seized caliper.
Is Your 2011-2017 Buick Regal Experiencing Brake Problems?
A faulty brake caliper can cause a range of unnerving symptoms. Many Regal owners have reported issues with calipers sticking, particularly in high heat. This can feel like the car is dragging, cause the steering wheel to shake violently, and lead to a burning smell from the wheels after a drive. Other common signs of a failing caliper include the car pulling to one side when braking, a soft or spongy brake pedal, or visible brake fluid leaks on the inside of your wheels.

A Technical Service Bulletin (TSB PIC5692A) was issued for 2011-2012 Regals for a sticking brake pedal caused by a binding pivot bushing, especially in high heat and humidity. This can create symptoms—like dragging brakes—that are very similar to a seized caliper. If your brakes are dragging, it's wise to consider this TSB as a possible cause along with the caliper itself.
Choosing the Right Aftermarket Caliper for Your Regal
One of the most important steps is identifying which brake system your Regal has. Most models use a standard single-piston floating caliper. However, the high-performance Regal GS model is equipped with larger, 4-piston Brembo fixed calipers on the front wheels. These two systems use completely different calipers and are not interchangeable. Always verify your specific model before ordering.
Aftermarket Brand Tiers
- OEM-Equivalent Brands (ACDelco): As the original equipment provider for GM, ACDelco offers calipers that are a direct replacement for the factory parts. They are a reliable choice for owners seeking to restore original performance and fit.
- Premium & Performance Brands (Powerstop, Dynamic Friction): Brands like Powerstop are known for offering calipers that are 100% pressure tested and often feature powder coatings (like their signature red) to resist rust and corrosion. These are a great option for drivers looking for enhanced durability, longevity, and a sportier look, especially for the Regal GS. 🎬 See this walkthrough for replacing front Brembo brakes
- Standard Aftermarket Brands (Cardone, Raybestos, Centric): These brands are staples of the aftermarket and provide a good balance of quality and value. They offer both new and remanufactured calipers that meet or exceed original specifications, making them a solid choice for daily driving and budget-conscious repairs.
New vs. Remanufactured
Remanufactured calipers are original caliper castings that have been cleaned, inspected, and rebuilt with new seals, boots, and pistons. They are a cost-effective and environmentally friendly option. New aftermarket calipers are made from 100% new components. For a daily driver, a quality remanufactured caliper from a reputable brand is often perfectly sufficient.
Estimated Costs for Brake Caliper Replacement
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Caliper (per wheel) | $59 - $160 |
| Shop Labor (per wheel) | $125 - $255 |
| Total Estimated Cost (per wheel) | $184 - $415 |
Costs are estimates and can vary based on location, part brand, and specific vehicle configuration (standard vs. GS). It is highly recommended to replace calipers in pairs (both front or both rear) for balanced braking.
Frequently Asked Questions
Do I need special tools to replace my Regal's calipers?
For the front calipers, standard hand tools are generally sufficient. However, the rear calipers on the 2011-2017 Regal require a special brake caliper tool to simultaneously push and turn the piston back into its housing. This is necessary due to the integrated parking brake mechanism. Attempting to compress it with a standard C-clamp will damage the caliper.

The Brembo brakes are standard on the Regal GS trim. They are large, typically painted (often red or silver), and may have the "Brembo" logo visible through the wheel spokes. Standard calipers are smaller, unpainted cast iron. If you are unsure, check your vehicle's original specifications or visually inspect the caliper.
Should I replace my brake calipers in pairs?
Yes. It is always recommended to replace calipers on the same axle at the same time. This ensures that both sides have the same braking force, preventing the car from pulling to one side and ensuring even pad wear.
What other parts should I replace with the caliper?
When you replace a caliper, you should also install new brake pads and hardware. It is also the perfect time to inspect the brake rotor for wear and the brake hose for cracks or leaks. The brake system must be bled to remove any air that entered when the old caliper was disconnected. Always use fresh, correct-spec brake fluid.
