Servicing Your Honda 117

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 25, 26).

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 (2) 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 114) and the securing bolts are tight.

Make sure there are no fluid leaks. Check for

deterioration or cracks in the hoses and fittings.
