Clutch Fluid: Testing and Inspection

HYDRAULIC CLUTCH FLUID LEVEL CHECK

NOTICE:
- Do not use mineral oil or a paraffin base oil in the hydraulic system. These fluids will damage the rubber parts in the cylinders. Only DOT 3 brake fluid should be used.
- Carefully clean the cap and sides of the brake reservoir before removing to prevent contamination of the system with dirt, water or other foreign material. Carefully replace the cap after filling.





The fluid for the clutch system is provided from the brake master cylinder reservoir. There are only two reasons why the brake fluid in the reservoir might go down. First, the brake fluid level will go down due to normal brake lining wear. When new linings are installed, the fluid level will go back up. Second, the brake fluid will drop if the brake system or clutch hydraulic system develops a leak.
If the brake master cylinder requires any fluid, check both the brake and clutch hydraulic systems for leaks. Repair any leaks or replace any faulty components found.
