3. Install:

  • Rear wheel Refer to "REAR WHEEL" on page 4-12.

4. Fill:

  • Brake fluid reservoir (with the specified amount of the recommended brake fluid)

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.
CAUTION:

Brake fluid may damage painted surfaces and plastic parts. Therefore, always clean up any spilt brake fluid immediately.

5. Bleed:

  • Brake system Refer to "BLEEDING THE HYDRAULIC BRAKE SYSTEM" on page 3-20.

6. Check:

  • Brake fluid level Below the minimum level mark "a"
