Brake fluid level check
Insufficient brake fluid may let air enter the
brake system, possibly causing the brakes to
become ineffective.
Before riding, check that the brake fluid is
above the minimum level mark and replenish
if necessary. A low brake fluid level may indi-
cate worn brake pads and/or brake system
leakage. If the brake fluid level is low, be sure
to check the brake pads for wear and the
brake system for leakage.
1. Minimum level mark
Observe these precautions:
● When checking the brake fluid level, make
sure the top of the brake fluid reservoir is
level.
● Use only the designated quality brake fluid,
otherwise, the rubber seals may deterio-
rate, causing leakage and poor brake per-
formance.
● Refill with the same type of brake fluid. Mix-
ing fluids may result in a harmful chemical
reaction and lead to poor brake perfor-
mance.
● Be careful that water does not enter the
brake fluid reservoir when refilling. Water
will significantly lower the boiling point of
the fluid and may result in vapor lock.
