Product Information
Full details
The TRP Hy/Rd Post Mount Caliper is designed for cyclists seeking enhanced hydraulic braking performance on their road or cyclocross bikes, especially those using disc brakes. Its primary benefit is improved stopping power and modulation compared to traditional mechanical disc brakes. A key consideration is its compatibility with specific shift levers, requiring verification before purchase. This caliper utilizes an open hydraulic system, features self-adjusting hybrid pistons for consistent pad wear compensation, and is a lightweight solution for performance-oriented riders.

FAQs
Is the TRP Hy/Rd caliper compatible with all road bike shifters?
No, it is specifically designed for use with Shimano and SRAM 11-speed road shift levers. Compatibility with specific models should be verified with TRP.
Do I need to buy rotors and adapters separately?
Yes, rotors and mounting adapters are sold separately and are not included with the caliper.
What is an 'open hydraulic system'?
An open hydraulic system allows fluid to flow freely between the caliper and reservoir, typically requiring a specific bleeding process. It generally offers easier pad wear compensation.
How often should I bleed the brakes?
The frequency depends on riding conditions and usage, but typically, bleeding is recommended annually or if you notice a spongy lever feel.
Can I use this caliper for mountain biking?
While the hydraulic performance is enhanced, the Hy/Rd caliper is specifically optimized for road and cyclocross applications and may not be suitable for the demands of mountain biking.
What is the weight of the TRP Hy/Rd caliper?
The TRP Hy/Rd caliper weighs approximately 0.35 pounds.
Troubleshooting
Brake lever feels spongy or lacks power.
The hydraulic system may need bleeding. Follow the manufacturer's specific bleeding procedure for the Hy/Rd system. Ensure all connections are secure.
Brakes are noisy (squealing).
Check pad alignment and ensure they are making full contact with the rotor. Clean the rotor and pads with isopropyl alcohol. Bed in the pads and rotor according to TRP recommendations.
Caliper is rubbing against the rotor.
Center the caliper over the rotor by adjusting the mounting bolts. Ensure the rotor is true and not warped. Check that the Post Mount adapter is correctly installed.
Brake pads are not returning fully.
Verify that the hydraulic system is properly bled and there are no air bubbles. Ensure the pistons are moving freely and the brake line is not kinked.
Pros and Cons
Pros
- Offers superior hydraulic braking performance for road and cyclocross applications.
- Compatible with widely used 11-speed Shimano and SRAM road shift levers.
- Self-adjusting pistons maintain consistent braking as pads wear.
- Lightweight construction minimizes impact on overall bike weight.
Cons
- Requires separate purchase of adapter and rotor.
- Compatibility with shift levers needs to be confirmed with the manufacturer.
- Open hydraulic system may require specific bleeding procedures.
Setup, Compatibility & Care
Setup: The TRP Hy/Rd caliper uses the standard Post Mount interface. Ensure you have the correct Post Mount adapter if your frame or fork requires it, as adapters and rotors are sold separately. Follow the manufacturer's instructions for hydraulic line routing and connection to your shift levers. Proper bleeding of the hydraulic system is crucial for optimal performance.
Compatibility: This caliper is designed for use with 11-speed road shift levers from Shimano and SRAM. Due to the open hydraulic system, it is crucial to verify compatibility with your specific shift lever model. Contact TRP or consult their resources for a definitive compatibility list before installation.
Care: Regularly inspect brake pads for wear and clean the caliper body with a damp cloth. Avoid abrasive cleaners. Ensure the hydraulic fluid is free from contamination. Periodically check the brake lines for any signs of damage or leaks.
