Product Information

Full details

The Hope Tech 4 EVO GR4 Hydraulic Disc Brake is designed for gravity riders and e-bike users seeking maximum stopping power and confident control. Its key benefit is a significant increase in braking force with a more predictable, responsive lever feel, thanks to its advanced cam mechanism and revised four-piston caliper. A potential caveat is that rotors are sold separately and must be chosen to match your specific riding needs.

FAQs

Do I need special tools to bleed the Hope Tech 4 EVO GR4 brakes?

Yes, a specific bleed kit compatible with Hope brakes, along with DOT 5.1 brake fluid, is required for bleeding the system.

What is the difference between the Tech 4 EVO GR4 and previous Tech 4 models?

The GR4 model features a one-piece caliper, larger pistons, and a new cam mechanism for improved power, engagement speed, and heat management, delivering 6% more braking force.

Are the rotors included with the brake set?

No, rotors are sold separately. You will need to select compatible rotors based on your size and braking needs.

Can I use these brakes on a standard trail bike?

While designed for gravity and e-bikes, they can be used on trail bikes if the rider desires maximum stopping power. However, consider that their power might be more than necessary for lighter riding styles.

How often should I bleed my brakes?

Brake bleeding frequency depends on riding conditions and usage. For demanding use, bleeding every 6-12 months is recommended, or whenever the lever feel becomes spongy.

What is the warranty period for this brake set?

Please refer to the official Hope warranty documentation for the most accurate and up-to-date information regarding warranty periods and coverage.

Troubleshooting

Brake lever feels spongy or has excessive free stroke.

The brake system may need bleeding. Follow the Hope Tech 4 EVO GR4 bleeding procedure carefully. Ensure all connections are tight and check for air ingress.

Reduced braking power.

Check brake pad wear and rotor condition. Ensure the rotor is clean and free from contamination. Verify that the caliper is properly aligned with the rotor and that the pistons are moving freely.

Brake lever is stiff or sticky.

Inspect the master cylinder and piston seals for dirt or damage. Ensure the brake lines are not kinked. Light lubrication of external piston surfaces may help if they are exposed to debris.

Brake noise (squealing or grinding).

Clean rotors and brake pads. Bed in new pads and rotors properly. Ensure brake pads are correctly installed and not contaminated with oil or grease.

Pros and Cons

Pros

  • Exceptional stopping power for demanding downhill and e-bike use.
  • Predictable and confident braking with reduced free stroke.
  • Consistent performance under heavy loads and long descents.
  • Durable and stiff construction for precise control.
  • Easier maintenance with integrated bleed port.

Cons

  • Rotors are sold separately, requiring an additional purchase.
  • Higher performance may require specific setup adjustments for optimal results.
  • Advanced features may result in a higher price point compared to entry-level brakes.

Setup, Compatibility & Care

Setup: Ensure proper brake line routing and connection. The Tech 4 EVO GR4 is designed for use with Hope rotors (sold separately). Follow the manufacturer's instructions for bleeding the system to achieve optimal performance. Ensure the caliper mounting and lever positioning are set for rider comfort and optimal ergonomics.

Compatibility: This brake set is compatible with most modern mountain bike frames and forks designed for hydraulic disc brakes. The revised bore cap offers improved clearance for tighter frame designs. Always check frame and fork specifications for clearance.

Care: Regular cleaning of the caliper and rotor is recommended. Periodically inspect brake pads for wear and replace as needed. Periodic brake bleeding, as per the manufacturer's guidelines, will maintain optimal performance and lever feel. Avoid using abrasive cleaners directly on the braking surfaces.
