b. Brake pad wear and replacement
When you check your brake pads due to fallng performance, check ther
thckness. If they are less than 1 mm (Fg. 16), they wll need replacng.
To fit new pads, remove the brake callper from the fork or frame by
unscrewng allen bolts D(Fg.17). Unscrew (ant-clock wse), the smaller
allen bolt nsde allen bolt B(Fg.14). Lft up and pull the nner pad
downward, usng the protrudng part. Slde a thn slot screwdrver under
the outer pad and lft t up. Hold the screwdrver n ths poston and
remove the pad wth a par of longnosed plers.
Remove the sprngs from the worn out pads and fit them onto the new
pads. Replace the new pads, keepng them slghtly nclned nto the seat
of the Calper. Check that the sprng hooks correctly onto the small
pston.(When pullng downwards the pads should not come out).Refit the
Calper to the fork or frame and adjuster screw C(Fg.15)untl the pads
and the dsc are centered and the wheel spns freely. Agan there may be
some nose from the brake untl t “bed” n.
Step 6 Deralleur Gears Mantenance and Adjustment
To ensure that your deralleur gear works efficently and to prolong ts lfe,
t must be kept clean and free from excessve drt bult up and should be
properly lubrcated.
Note: If the specfic nstructon manual s provded accompaned wth
your bke, please follow t.
Before Adjustment, please make sure of the followng detals:
• The rght shfter controls the rear deralleur and sprocket.
• The largest rear sprocket generate low gear for hll clmbng; the small
rear gear sprocket develop hgh gear ratos for speed work and
