IMPORTANT Make sure your handle bar grips are always intact, in good condition and
on the bike. Uncovered handlebar tubes can be very dangerous in case of a collision.
14 Brakes
14.1
Front and Rear: V brake
14.2
The brakes on your Wisper bike are fitted with cut outs which are required by
law. This means that when you pull on either the back or front brake lever the
motor immediately stops working.
14.3
Full details of how to adjust and maintain your brakes:
Once a month, inspect brake pads for wear. If the grooves in the braking
surface are less than 2 mm deep, replace the pads.
V brake:
14.3.1.
Use 5mm Allen key to loosen bolt A,
then take the cable out. Use 5mm Allen
key to loosen bolts C (right & left), then
take the spacers and washers out
14.3.2.
Install new brake pads, then with both
pads pressed against the wheel rim,
ensure that distance B (in the diagram)
does not exceed 65mm. To decrease
distance B, exchange wide & narrow
spacers on each brake pad. Before finally
tightening brake pads, make sure they are aligned correctly on the rim,
and there is a gap of 1mm between the top of the rim and the top of the
pad. Hold each pad against the rim (one at a time) & tighten bolt C.
Finally tighten to 6-8N.M
14.3.3.
Insert cable into bolt A, slot cable guide pipe into holder and fit
protector over the guide pipe end. Set cable in bolt A so that combined
pad/rim clearance (the gaps from left pad to left rim surface and from
right pad to right rim surface) is 2mm, then tighten “A” bolt. Finally
tighten to 6-8N.M.
Balance brake arms by turning screw D. Depress brake lever a few times
while checking to see that tension is equal for both arms. Pad/rim
contact should occur at the same time each side. Clearance should be
1mm each side. Do not set tensions too high.
14.3.4.
Re adjusts pads so they are properly aligned (see step 2), as tension
adjustment will probably have altered the original pad alignment.
14.3.5.
Installing brake pads.
14.3.5.1.
Position each pad on an opposite side of the holder so that
two breaking surfaces are facing each other.
