Servicing Your Honda 125
Brakes
Brake pad wear depends on the severity of usage
and track conditions. (Generally, the pads will
wear faster with wet and dirty track conditions.)
Inspect the brake pads at each regular maintenance
interval (pages 36, 37).
Front Brake Pads
Inspect the brake pads (1) through the front wheel
to determine the brake pad wear. If either brake
pad is worn anywhere to a thickness of 0.04 in (1.0
mm), both brake pads must be replaced.
Rear Brake Pads
Inspect the brake pads (1) from the rear side of the
caliper to determine the brake pad wear. If either
brake pad is worn anywhere to a thickness of 0.04
in (1.0 mm), both brake pads must be replaced.
Check that the front brake lever and rear brake
pedal assemblies are positioned properly
(page 122) and the securing bolts are tight.
Make sure there are no fluid leaks. Check for
deterioration or cracks in the hoses and fittings.
Check the operation of the brake light switch (1).
Hold the brake light switch and turn the adjusting
nut (2) in the direction A if the switch operates too
late, or turn the nut in the direction B if the switch
operates too soon.
