Buick Regal 2018-present Brakes Specifications

The 2018-Present Buick Regal features ventilated front and solid rear disc brakes. Front brake rotors are typically 12.6 inches in diameter, and rear rotors are 11.8 inches. The brake system is compatible with the vehicle's electronic stability control and anti-lock braking system (ABS). Brake pads are designed for optimal performance and longevity, suitable for both standard and Sportback models from 2018 onwards.

Regular brake maintenance is crucial. Inspect brake pads every 15,000 miles and replace them when worn below 1/8 inch. Brake fluid should be changed every 30,000 miles or as indicated by the vehicle's maintenance schedule. Rotors should be resurfaced or replaced if warped or worn. Always check for brake fluid leaks and ensure proper ABS function.

To replace brakes, start by safely lifting the vehicle with a jack and securing it with jack stands. Remove the wheels, then the calipers, and suspend them without disconnecting the brake hoses. Inspect rotors; replace if necessary. Install new brake pads, ensuring proper alignment. Reattach calipers and bleed the brake system to remove air. Test the brakes with a slow drive to ensure proper function.

Common issues include a spongy brake pedal, which may indicate air in the system. If brakes drag, check for debris or warped rotors. Noise could signal worn pads or glazed rotors. Inspect pads, rotors, and fluid levels. Bleed the system if air is suspected. Consult a professional if issues persist for accurate diagnosis and repair.

For optimal braking, use high-friction brake pads and ensure rotors are clean and free of debris. Regularly flush and replace brake fluid with high-performance DOT 4 fluid. Keep wheels and tires compatible with the vehicle's braking system. Avoid aggressive driving to reduce wear and ensure even pad and rotor wear.
