The Hope Tech Piston Spring – HBSP231 is a genuine replacement internal spring designed specifically for Hope Tech hydraulic brake calipers.
This piston spring helps return the brake pistons to their resting position after actuation, ensuring smooth, consistent lever feel and reliable modulation. Over time, springs can fatigue or weaken, leading to inconsistent brake response or sluggish retraction. Replacing the spring with a fresh HBSP231 helps restore optimal brake performance and longevity.
