What calipers are used in the Regal GS Elite Edition?

[EloiseRose]

The Regal GS Elite Edition uses Brembo calipers. About calipers: A caliper is a tool for measuring length, divided into dial calipers and non-dial calipers. Usage methods include the steel ruler measurement method and the caliper measurement method. External calipers are used to measure the outer diameter of cylinders or the length of objects. Internal calipers are used to measure the inner diameter of cylindrical holes or the width of slots. How to use calipers: When taking measurements with external calipers on a steel ruler, one measuring face of the caliper rests against the end of the steel ruler, while the other measuring face aligns with the desired measurement mark. The line connecting the two measuring faces should be parallel to the steel ruler. When using internal calipers, the method is similar to external calipers, except that the end of the steel ruler must rest against an auxiliary plane, and one foot of the internal caliper also rests against this plane.

I've studied the configuration manual of the Regal GS Elite Edition, and it comes standard with Brembo high-performance calipers, featuring four-piston setups on both front and rear wheels. Those bright red calipers are particularly eye-catching, with a noticeably larger diameter compared to the regular Regal, giving it an aggressive look. In actual driving, the braking is impressively linear—just a slight press delivers significant stopping power, unlike some cars that feel mushy in the initial pedal travel. The heat dissipation design is also excellent, preventing noticeable fade even during continuous mountain driving. My friend tested it at a track day right after picking up the car, and the stock brakes performed adequately, though he later upgraded to more track-oriented brake pads.

Last year during the test drive of the Regal GS Elite Edition, I paid special attention to the braking system. Official documentation states that all models come standard with Brembo four-piston front calipers paired with large 345mm ventilated discs. The pedal feel is very firm, and body posture remains remarkably stable during emergency braking. GM has been quite generous this time, equipping even the entry-level performance version with track-grade calipers. I recall the 4S store salesperson mentioning that the calipers are imported from Italy, and later maintenance can source genuine parts through official channels. The standard Regal uses single-piston floating calipers, which are visually inferior by comparison.

Buick has equipped the entire Regal GS lineup, including the Elite trim, with Brembo-sourced opposed four-piston calipers. The most impressive feature of this braking system is its resistance to heat fade. After continuously driving over ten kilometers of mountain roads, the brake pedal feel remains firm. The caliper body is made of cast aluminum alloy, which is 2.3 kg lighter than traditional single-piston calipers. The paired brake pads have a friction coefficient of 0.45, providing sufficient braking force even when cold. Some owners have tested the 100-0 km/h braking distance, with the Elite trim consistently achieving under 35 meters. The factory also includes metal brake lines for more direct braking force transmission during aggressive driving.

The vibrant red calipers visible inside the wheel rims tell the story – the Regal GS Elite Edition comes standard with Brembo front four-piston braking system. Specifically, it's equipped with F50 four-piston calipers paired with 345x30mm ventilated discs. GM engineers stated these calipers underwent five rounds of track testing, maintaining stable braking force even under high-temperature conditions. I've measured the caliper piston sizes – two 42mm pistons on each side. The most noticeable daily driving experience is that braking doesn't require deep pedal pressure; just gentle application gives deceleration feel, and rear wheels are less prone to locking up after rain.
