Replacement brake caliper for M3's and M4's equipped with M Carbon ceramic brake (S2NKA)
Brake calipers are the mechanical component that squeeze the brake pads into the brake rotor surface. The brake calipers are controlled via the input from the brake master cylinder. For the most part, brake calipers are simply mechanical devices but they are critical for vehicle safety and performance.
Brake calipers are a lifetime component for the most part. However, brake calipers are exposed to some extreme conditions including heating and cooling cycles which can cause performance issues later on in service life. Brake caliper failures usually occur when the square cut seal inside the caliper piston bore degrades and cause the piston to stick. A sticking piston or multiple sticking pistons will cause improper caliper performance and can even cause the brake pads to drag on the brake rotor.
Many brake calipers can be repaired with new seals but many prefer to simply install new brake calipers to save time and to prevent future complications from improper repairs.
