Brake performance hinges on the foundation brake system—the parts that actually apply friction to slow the wheels. When performance problems arise, they almost always come from wear, sticking, or failure within those components: worn pads or shoes, glazed or warped rotors/drums, sticking calipers or wheel cylinders, and any leaks or air in the hydraulic lines that reduce pressure and pedal feel. These mechanical and hydraulic issues directly limit braking force and control.

Electrical controls like ABS or stability systems can modify braking behavior, but they don’t originate the basic loss of braking power. Tire design affects how well those brakes’ force translates into stopping grip on the road, and engine lubrication doesn’t directly influence brake performance.
