The Hope Tech 4 Evo TR4 is designed for trail and all-mountain riders who demand precise braking control and consistent modulation without sacrificing power. It serves as an ideal upgrade for riders seeking a firmer lever feel and a 6.5% increase in braking ratio over previous E4 systems, though riders should note that rotors are not included and must be purchased separately to complete the installation.

No, rotors are not included and must be purchased separately.
Yes, the TR4 caliper is compatible with standard Hope rotors used with the E4 series.
Hope hydraulic disc brakes use DOT 5.1 brake fluid.
Yes, the master cylinder features a dedicated bleed port designed specifically for this purpose.
The Tech 4 has redesigned ergonomics with an increased hook, a lighter lever action, and a new cam design for a firmer bite point.
The system likely has air trapped in the master cylinder. Use the new bleed port to perform a secondary bleed to purge air.
Clean the pistons with isopropyl alcohol and a lint-free cloth. Ensure the guide bushes are clear of debris.
Ensure the pads have been bedded in correctly by performing a series of controlled stops on a flat surface to transfer material to the new rotor.
Installation requires standard hydraulic brake mounting procedures. Ensure your frame or fork has the appropriate post-mount or adapter configuration for the TR4 caliper. Because the master cylinder now includes a secondary bleed port, maintenance is significantly simplified compared to older Hope models. To bleed the system, you can use either the traditional open-lid method or the new dedicated bleed port. Periodically check the GR4 pads for wear, especially after muddy or wet rides. Keep the lever pivot clean and ensure the hose is routed away from sharp bends to prevent hydraulic flow restrictions. Note that this unit comes with the lever pre-bled; however, you will need to trim the hose length to match your cockpit setup, which will necessitate a fresh bleed.
