FAQs

Are the rotors included with this brake?

No, the Hope Tech 4 EVO TR4 does not include rotors. They must be purchased separately based on your wheel size and mounting requirements.

What type of brake pads does this system use?

This brake uses the Hope GR4 pad series, which provides a larger contact area for improved consistency and durability.

Can I use this brake for downhill racing?

While the TR4 is excellent for trail and all-mountain use, Hope offers specialized systems if you are exclusively riding heavy-duty downhill courses.

Is this brake compatible with existing Hope mounts?

Yes, it is generally compatible with standard Hope mounting hardware, but always verify your specific frame adapter needs.

How often should I bleed the brakes?

It is recommended to bleed your brakes at least once a year, or sooner if you notice a change in the lever feel or reduced responsiveness.

Troubleshooting

Lever feels spongy or lacks a firm bite

The system likely contains trapped air. Perform a full bleed using the integrated bleed port and official Hope hydraulic fluid.

Brake pads dragging against the rotor

Ensure the caliper is correctly centered over the rotor and that the pistons are not stuck. Push the pistons back into the caliper body and re-center.

Reduced braking performance

Check pads for oil contamination. If contaminated, clean the rotor with isopropyl alcohol and replace the brake pads.

Pros and Cons

Pros

  • Superior modulation and precise braking feedback
  • Firm and consistent lever feel even on long descents
  • High-stiffness one-piece caliper construction
  • Simplified bleed process via integrated port

Cons

  • Rotors are not included with the brake assembly
  • Requires specific technical knowledge for installation and bleeding
  • Higher entry price point compared to entry-level trail brakes

Setup, Compatibility & Care

Installation of the Hope Tech 4 EVO TR4 should be handled with care to ensure the hydraulic lines are routed correctly for your frame's internal or external cable routing. Because the caliper is a one-piece design, ensure the mounting bolts are torqued according to manufacturer specifications to prevent uneven wear. For compatibility, ensure you are using rotors that match the required diameter for your frame and fork, as these are sold separately. Periodic maintenance includes checking the GR4 brake pads for wear and flushing the hydraulic system through the integrated bleed port annually or if the lever feel becomes inconsistent.
