NOTE:
- Place the vehicle on a suitable stand.

2. Check:
Brake fluid level Below the minimum level mark "a" → Add the recommended brake fluid to the proper level.

A. Front brake
B. Rear brake
WARNING- Use only the designated brake fluid. Other brake fluids may cause the rubber seals to deteriorate, causing leakage and poor brake performance.
- Refill with the same type of brake fluid that is already in the system. Mixing brake fluids may result in a harmful chemical reaction, leading to poor brake performance.
- When refilling, be careful that water does not enter the brake fluid reservoir. Water will significantly lower the boiling point of the brake fluid and could cause vapor lock.
Brake fluid may damage painted surfaces and plastic parts. Therefore, always clean up any spilt brake fluid immediately.
NOTE:
In order to ensure a correct reading of the brake fluid level, make sure the top of the brake fluid reservoir is horizontal.
