9.3 Flex the brake hoses and check for
cracks, bulges and leaking fluid
2 Check the brake lever and pedal for loose
connections, improper or rough action, excessive
play, bends, and other damage. Renew any
damaged parts (see Chapter 7). Clean and
lubricate the lever and pedal pivots if their action
is stiff or rough (see Section 18).
3 Make sure all brake fasteners are tight. Check
the brake pads for wear (see Section 8) and
make sure the fluid level in the reservoirs is
correct (see Daily (pre-ride) checks). Look for
leaks at the hose and pipe connections and
check for cracks in the hoses and pipes
themselves (see illustration). If the lever or
pedal is spongy when applied, bleed the brakes
(see Chapter 7).
4 Make sure the brake light operates when the
front brake lever is pulled in. The front brake light
switch, mounted on the underside of the master
cylinder, is not adjustable. If it fails to operate
properly, check it (see Chapter 9).
5 Make sure the brake light is activated just
before the rear brake takes effect. If adjustment
is necessary, hold the switch and turn the
adjuster ring on the switch body until the brake
light is activated when required
illustrations). If the brake light comes on too
late, turn the ring clockwise. If the brake light
comes on too soon or is permanently on, turn the
ring anti-clockwise. If the switch doesn't operate
the brake light, check it (see Chapter 9).

6 On TDM and TRX models, the front brake
lever has a span adjuster which alters the
distance of the lever from the handlebar (see
illustrations). Each setting is identified by a
number on the adjuster which aligns with the
arrow on the lever bracket. Pull the lever away
from the handlebar and turn the adjuster ring
until the setting which best suits the rider is
(see
obtained. There are four settings.
7 On XTZ models, the front brake lever has a
freeplay adjuster which alters the amount of play
in the lever before the brake takes effect. Check
the amount of freeplay by measuring the distance

compare it to the amount specified at the
beginning of the Chapter. To adjust the freeplay,
slacken the adjuster locknut and turn the adjuster
as required until the specified amount of freeplay
is achieved (see illustration). Turn the adjuster

clockwise to increase it.
Caution: Make sure that the correct amount of
freeplay is set. Insufficient freeplay could
cause the brakes to bind and excessive
freeplay may not allow them to operate to
their full potential.
