Acura MDX 2014-2020 Brakes Specifications

The 2014-2020 Acura MDX features a braking system with 12.6-inch ventilated front brake rotors and 12-inch solid rear brake rotors. The front brakes are equipped with dual-piston calipers, while the rear brakes use single-piston calipers. The system is compatible with brake pads designed for high-performance vehicles, with a minimum friction rating of μ=0.35. The brake fluid recommended is DOT 3 or DOT 4 synthetic. The MDX's ABS system includes electronic brake distribution (EBD) and brake assist for enhanced stopping performance.

The brakes on the 2014-2020 Acura MDX require regular inspection every 15,000 miles. Brake pads should be replaced when worn down to 1/8 inch or less. Rotors should be inspected for warping or excessive wear and replaced if necessary. Brake fluid should be changed every 30,000 miles or as specified in the maintenance schedule. Additionally, the brake system should be bled every 60,000 miles to remove air and moisture. Always use OEM or equivalent parts to maintain system performance and reliability.

To replace the brakes on a 2014-2020 Acura MDX, start by raising the vehicle and removing the wheels. Remove the caliper bolts and slide the caliper off the rotor, taking care not to damage the brake hose. Remove the old brake pads and install the new ones, ensuring proper alignment. If replacing rotors, remove the rotor retaining screws and replace the rotor with a new one. Reinstall the caliper and tighten the bolts in a star pattern to the specified torque (typically 30-40 ft-lbs). Bleed the brake system to ensure proper function and test the brakes before driving.

Common brake issues on the 2014-2020 Acura MDX include squealing noises, spongy brake pedal feel, or reduced stopping power. For squealing brakes, inspect the brake pads for wear or contamination. A spongy pedal may indicate air in the brake lines, requiring system bleeding. Reduced stopping power could be due to worn brake pads, warped rotors, or low brake fluid levels. Always inspect the brake fluid level and condition, and check for any signs of fluid leaks. Refer to the service manual for detailed diagnostic procedures and repair steps.

To optimize the performance of the brakes on a 2014-2020 Acura MDX, use high-quality brake pads designed for your driving conditions. Ensure proper bedding-in of new brake pads by gradually increasing stopping force over several miles. Maintain the recommended brake fluid level and use synthetic brake fluid for improved heat resistance. Avoid aggressive driving and excessive heat buildup by maintaining a safe distance from the vehicle in front of you. Consider upgrading to performance rotors with cross-drilled or slotted designs for improved cooling and reduced fade.
