Both the clutch and brake fluid master cylinders require brake fluid that meets or exceeds DOT 3 standards.
Both the clutch and brake master cylinders have translucent reservoirs which enable the fluid level to be checked without removing the reservoir cap. The clutch fluid level should at or above the step in the reservoir body. The brake fluid level should be between the MIN and MAX lines located on the side of the reservoir.
If it is necessary to add fluid, first wipe away any accumulated dirt or grease from the reservoir. Then remove the reservoir cap by twisting counter clockwise. Add fluid to the proper level. Avoid spilling brake fluid on any painted surface as it will harm the finish. Replace the reservoir cap.
