Perfectly Even Piston Reset Every Time!

“Brake pad replacement felt much more controlled using this tool. The pistons retracted evenly without tilting, and the caliper stayed properly aligned, resulting in a smooth and consistent brake feel afterward.” - B. Platt

Why Get Our Bicycle Disc Brake Caliper Piston Press Tool?

✅ Even & Controlled Piston Compression: Uneven piston retraction during brake pad replacement can cause piston tilt, seal stress, and inconsistent braking performance. This piston press tool delivers flat, evenly distributed pressure across the piston surface, allowing smooth and controlled retraction that helps maintain proper caliper alignment and reliable brake function after servicing.

✅ Multi-Piston Calipers Compatibility: Designed for hydraulic disc brake systems using wider piston spacing, this tool supports both two-piston and four-piston bicycle brake calipers. With a pressing width of 1.1 inches (2.8 cm), it provides stable contact across pistons for uniform compression. It is suitable for many high-performance hydraulic calipers but is not compatible with narrow two-piston designs.

✅ Precision CNC Aluminum Build: Constructed from solid aluminum using a full CNC machining process, the tool offers excellent rigidity, corrosion resistance, and dimensional accuracy. The strong, non-flexing structure ensures consistent performance over repeated use, making it ideal for both home maintenance and professional workshop applications.

📓FREQUENTLY ASKED QUESTIONS

Q: How does the piston press tool work during brake pad replacement?

A: The tool applies flat, evenly distributed pressure to the caliper pistons, allowing them to retract smoothly and evenly without tilting or stressing internal seals.

Q: Is this tool suitable for both two-piston and four-piston calipers?

A: Yes, it is designed to work with compatible two-piston and four-piston hydraulic disc brake calipers that require a wider press surface.
