Technical Specifications

Designed for Serious Off-Road Performance

The Brembo 10x19 setup is specifically tuned for riders who want a strong yet highly controllable front brake feel. The smaller 10mm piston increases hydraulic leverage and improves brake modulation, making it especially effective in technical off-road riding where traction and precision are critical. Riders commonly note that smaller piston master cylinders provide increased lever travel and improved feedback.

This master cylinder has become a benchmark choice for Enduro and MX racing thanks to its predictable braking response, excellent reliability, and consistent performance under extreme conditions.

Installation Notes

When upgrading your brake master cylinder, additional components may be required:

• External brake fluid reservoir or reservoir mounting kit
• Compatible banjo bolt(s)
• Fresh DOT 4 brake fluid
