How Many Pistons Does a Family Car's Brake Caliper Have?

[MacAyla]

Family car brake calipers are single-piston. Location of brake pistons: As the component that applies force to the brake disc, the brake piston is naturally very important. Most ordinary family cars use single-piston calipers, typically located on the rear side of the brake disc, so only the caliper and the brake pads fixed on it are visible from the outside. Size differences: Some multi-piston calipers have pistons of varying sizes. Taking the most common six-piston caliper as an example, some manufacturers design all six pistons to be the same size, while others adopt arrangements like "large, medium, small," "large, small, medium," or "small, large, small." This not only ensures more even distribution of braking force and brake pad wear but also delivers more linear braking performance, providing greater braking power while reducing abruptness during the braking process.
