3.4. Shortening or re-routing the hose
Your disc brake is supplied fully assembled and bled by the Hope factory and the hose length will
suit the majority of forks and frames. If desired, the following procedure can be used to shorten the
hose. The same procedure can be used to detach the hose and route it through existing frame
guides.
The item numbers refer to the diagram of the Closed 2 caliper (download separately) but the
procedure is identical for all calipers.
1. Remove the wheel and brake pads to prevent contamination.
2. At the caliper end, unscrew the aluminium shroud (item 16) and slide it away from the connector
(item 22).
3. Prise open the brass olive (item 15) using a screwdriver and slide the olive away from the
connector.
4. Push the end of a small fine bladed screwdriver under the hose end and prise the hose away
from the connector. Once it has eased away from the connector it should be possible to detach
the hose by gently pulling it. This operation must be done carefully or the inner section of the
hose will separate from the outer. Caution, hold the separated hose carefully, the hose contains
brake fluid and it will leak out if you allow the hose to swing freely.
5. Cut the hose to the desired length using hose cutters or a sharp knife to produce a clean square
cut. Do not remove too much, the resulting hose length should still permit the full and
unrestricted movement of the handlebars.
At this stage the hose can be routed through existing fork or frame guides taking care not to kink
the hose. Take care to avoid a routing situation that can damage the hose when the bicycle is
used such as trapping the hose within suspension fork or rear suspension linkage movements
and avoid chaffing on the tire.
6. Push the hose onto the connector.
7. Slide the brass olive and aluminium shroud into position and tighten.
8. Re bleed the system as described in section 3.3.
3.5. Hose change
If the hose becomes damaged such that a system leak (however small) occurs then replace the
hose. Try to identify how the original damage occurred to prevent the same thing happening again.
A new length of genuine Hope Technology hydraulic hose will need purchasing. Follow the
procedure for shortening/re routing the hose in section 3.4. Note, in section 3.4, the hose is
disconnected from the lever in the same manner as described for disconnecting from the caliper.
3.6. Caliper half change – piston removal
This operation is required if you change your forks (or frame) to one that incorporates a different
disc mount design. In most cases you can utilise your existing Hope disc brake by changing the
caliper half to a new one that has the appropriate bolt mounting pattern. Consult your dealer who
will advise what caliper half is required.
This procedure can also be used should you need to remove a caliper piston.
1. Remove the wheel and brake pads to prevent contamination.
2. To obtain better leverage leave the caliper on the fork (or frame) and use an Allen key to just
release the tightness of the two caliper half retaining screws. Remove the caliper from the fork
(or frame), there is no need to disconnect the brake hose.
