Clutch Master Cylinder



When adding or changing the fluid in the hydraulic clutch system, use a quality brake fluid conforming to DOT 3 OR DOT 4 specifications such as HONDA® Brake Fluid, or equivalent. Never reuse old brake fluid.

Fig. Fig. 2: Adding fluid to the clutch master cylinder.

The fluid in the clutch master cylinder is key to the proper clutch actuation on your vehicle. Low levels of fluid indicate a need for service (there may be a leak in the system or the clutch pad lining may just be worn and in need of replacement). In any case, the fluid level should be inspected at least during every oil change, but more often is desirable. Every time you open the hood is a good time to glance at the master cylinder reservoir.

  1. Wipe the clutch master cylinder reservoir cap and the surrounding area clean with a shop towel.
  3. Inspect the fluid in the reservoir, making sure the fluid is between the MAX and MIN marks.
  5. If required, remove the clutch master cylinder reservoir lid, then add fresh fluid to bring the level up to the MAX mark on the reservoir.

When making additions of fluid, use only fresh, uncontaminated brake fluid which meets DOT 3 or DOT 4 standards. Do not allow the brake fluid container or the master cylinder to remain open any longer than necessary; brake fluid absorbs moisture from the air, reducing the fluid's effectiveness and causing corrosion in the lines.

Be careful to avoid spilling any brake fluid on painted surfaces, because the paint coat will become discolored or damaged.

  1. Reinstall the lid onto the clutch master cylinder.
