1. Introduction
Thank you for purchasing a Hope Technology disc brake system. Please read the contents of this
service manual to fully acquaint yourself with the correct installation and safe operation of your
brake.
1.1. Instruction manual coverage
This manual covers the installation and servicing of the Closed 2, Mini and M4 hydraulic disc
brakes.
1.2. Safety first
This brake system must be fitted by a competent cycle mechanic using the correct tools. Incorrect
installation can result in brake failure that can cause serious personal injuries.
Your braking performance will improve in almost all riding conditions but care must be taken to ride
within your own ability. The stopping power of any bicycle is always limited by the traction of the
tyre on the ground so take the time to become familiar with your new brake and its braking
characteristics.
Before each ride always check the brake for proper function and the brake pads for wear and that
there is no system damage resulting in fluid leaks.
If you have any doubts or questions please contact your dealer or the appropriate Hope distributor
for your country.
1.3. System identification
There are three current brake designs; the Closed 2 using the Pro lever, the Mini and M4 both
using the Mini lever
The Closed 2 is a closed system, while the Mini and M4 are both open systems.
The following table shows examples of each caliper. The caliper profiles can vary depending on
the disc rotor size and bolt mounting pattern and the table shows common examples.
