How to Count Brake Pistons?

[JakeDella]

When counting pistons, you only need to count one side (symmetrical), and the total number of pistons is the number of protrusions multiplied by two. Below is the relevant introduction: 1. Appearance: The number of brake pistons is easy to distinguish and can be identified from the appearance. There are several round protrusions on the caliper, and these protrusions are the pistons. The pistons on the caliper are symmetrically arranged on both sides, which not only increases braking force but also ensures even distribution of the braking force. 2. Single Piston: Most ordinary family cars use a single piston, usually located on the rear side of the brake disc, so only the caliper and the brake pads fixed on the caliper can be seen from the outside. Of course, many high-performance cars use multi-piston calipers, which provide excellent braking performance.
