Observe these precautions:
When checking the 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.
Recommended brake fluid: DOT 4
● Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reac-
tion and lead to poor brake performance.
