4. Fill the syringe with DOT 4 or DOT 5.1 brake fluid from a new
bottle:
Put the syringe in the bottle with the nozzle under the fluid level
and pull the piston of the syringe.
Use DOT 4 or DOT 5.1 brake fluid only.
DOT 4 and DOT 5.1 brake fluid should not be mixed.
Make sure that the syringe is filled with the same kind of fluid as in
the brake system.
The MPH brake sets have been filled by Giant with DOT 4 brake
fluid.
5. Push the syringe on the open end of the short transparent tube.
In case most of the brake fluid is still in the MPH disc brake system (for example after shortening a hose
or switching front- and rear brake from one side from the handlebar to the other) skip step 6 to 10 and
continue with step 11.
Otherwise, if there is no or almost no brake fluid inside the MPH disc brake system (for example when
replacing all the brake fluid once per year or 2 years, or after complete disassembly of the caliper and/or
the master cylinder), continue with step 6.
6. Take the bleeder cover (rubber cap) off from the calipers’ bleeder
and mount the second (long) transparent tube. Put the other end of
this tube into a bottle or cup that can contain brake fluid.
7. Unscrew the calipers’ bleeder just a bit with a wrench 10 mm.
(¼ to ½ turn).
8. Start squeezing the syringe and don't stop squeezing until it is
mentioned in this manual (step 10).
