The seals inside the master cylinder build and hold brake pressure. As they swell or harden with age, the lever turns spongy or slowly sinks toward the bar while braking fades. This kit reseals the cylinder and restores a firm lever and reliable pressure. Confirm your bore size before ordering so the seals match.
