The brake can be adjusted by simplay adjust-
ing the distance that the brake lever can
travel. (The piston in the caliper moves for-
ward as the brake pad wears out, automati-
cally adjusting the clearance between the
brake pad and the brake disc.)

Indicator cap
To check, open the wear indicator cap
and if any pad is worn to the red line, re-
place pads.
3. Check the brake fluid level
Insufficient brake fluid may allow air to
enter the brake system, possibly causing
the brake to become ineffective. Check
the brake fluid level and replenish when
necessary and observe these precautions:
a. Use only the designated quality brake
fluid; otherwise, the rubber seals may de-
teriorate, causing leakage and poor brake
performance.
Refill with the same type and brand of
brake fluid; mixing fluids may result in a
harmful chemical reaction and lead to
poor performance.
Be careful that water or other contamina-
tion does not enter the master cylinder
when refilling. Water will significantly
lower the boiling point and may result in
vapor lock.
E. Rear brake
1. Adjust rear brake pedal play to suit, pro-
viding a minimum of 20 30 mm (0.8
1.2 in) freeplay. Turn the adjuster on the
rear brake rod in or out until brake pedal
free play is suitable.
NOTE:
Rear brake pedal adjustment must be
checked anytime chain is adjusted or rear
wheel is removed and then reinstalled.
