Main Parameter

Note:
The DOT4 compound brake fluid is recommended to the clutch.
Unclean or dirty brake fluid is forbidden to use.
Do not splash the brake fluid down to the paint. (It may erode the paint.)
You must make use of the tools to disassemble and assemble the clutch pipeline system.
Make use of the clean brake fluid to clean the master cylinder, booster and the fluid reservoir.
The mining oil such as gasoline, kerosene, etc., it will erode the rubber parts in the hydraulic pressure sys-

tem.

After clean the clutch pressure plate, dry it with the suction cleaner, not the compression air.
