TRP HY/RD Disc Brake

Yes, the HY/RD is designed to be compatible with all standard cable-actuated road and cyclocross brake levers. It bridges the gap by using your existing cables to actuate the hydraulic master cylinder located directly on the caliper.

While the system is hydraulic, it is largely maintenance-free. You will rarely need to bleed the system, but it does use mineral oil if a bleed ever becomes necessary.

Standard mechanical brakes pull a cable to push the pads directly, which can feel stiff or inconsistent. The HY/RD uses that cable pull to activate a self-contained hydraulic piston, providing the smoother modulation, power, and automatic pad adjustment you would expect from a full hydraulic system.

No, the HY/RD features automatic pad wear compensation. The internal hydraulic system adjusts itself as the pads thin out, ensuring your lever feel remains consistent throughout the life of the brake pads.

These are specifically engineered for road and cyclocross geometry and leverage ratios. They are not intended for mountain bike use, as they are not compatible with MTB-specific brake levers.

The HY/RD is compatible with both standard rotors and resin-only rotors. Just ensure you are using the correct pad compound for your specific rotor type to prevent premature wear or reduced performance.
