FAQs

Are rotors included with the brake?

No, rotors are sold separately.

What type of brake pads does the TR4 use?

The TR4 uses shared GR4 pads, which are designed for balance and high performance.

Is this brake suitable for downhill racing?

While the TR4 is excellent for trail and all-mountain use, Hope offers dedicated V4 systems for extreme downhill racing applications.

How do I bleed the brake without removing the lid?

Utilize the integrated bleed port on the master cylinder to push fluid through the system using a bleed kit.

Can I use DOT fluid from an auto store?

It is highly recommended to use the official Hope hydraulic fluid or a high-quality DOT 5.1 fluid that meets the specifications required by the seal material.

Does the lever reach adjust easily?

Yes, the Tech 4 lever features an ergonomic reach adjustment dial that allows for tool-free modification.

Troubleshooting

Brake lever feels soft or pulls to the bar

The system likely contains air and requires a full bleed using the integrated bleed port.

Brakes are rubbing or not centered

Loosen the caliper mounting bolts, squeeze the brake lever firmly, and tighten the bolts while keeping the lever held.

Brakes are squealing during use

Clean the rotor with isopropyl alcohol and ensure the brake pads are not contaminated with oil or grease.

Setup, Compatibility & Care

Installation of the Hope Tech 4 EVO TR4 follows standard mountain bike disc brake procedures. Ensure the brake mounts on your frame and fork are clean and faced if necessary for optimal caliper alignment. When installing the hose, be aware that this specific model is designed for left-hand lever operation; ensure your cockpit setup is compatible. Regular care involves checking the brake pads for wear periodically, especially in muddy conditions, and performing a bleed if the lever feel becomes soft or spongy. Always use the specified Hope hydraulic fluid to maintain internal seal integrity. Keep the caliper pistons clean of debris during pad changes to ensure the guide bushings function as intended.
