In many modern vehicles with a manual transmission, the clutch is engaged and disengaged using a hydraulic system that is almost identical to a hydraulic brake system. The hydraulic fluid contained in the clutch master cylinder becomes pressurized when you press the clutch pedal. Pressurized fluid activates the slave cylinder (slave) and disengages the clutch. The clutch is in a dangerous position, being constantly engaged and may eventually burn out if the fluid level in the master cylinder is low.To maintain proper clutch performance, check the fluid level annually and change fluid as necessary. This article will explain how to add brake fluid to the clutch master cylinder in most conventional cars.

Steps

1. 1 Check the fluid level in the clutch system.
   • Park your vehicle on a level surface and turn off the engine.
   • Locate the clutch master cylinder reservoir. It is usually translucent and is installed next to the brake master cylinder.
   • Check the fluid level and make sure it needs to be added before proceeding.
2. 2 Buy the correct brake fluid. There is no clutch fluid. As a rule, brake and / or similar fluids are used in the operation of the clutch cylinder. Check your vehicle manual to see if there are any special requirements. But usually standard DOT3 or DOT4 brake fluids can be used in almost all vehicles.
3. 3 Wipe the master cylinder reservoir and cover with a dry, clean cloth to remove dirt and debris. Make sure there are no small particles around that could get into the tank.
4. 4 Remove the cap from the reservoir and add brake fluid. Use the minimum and maximum marks on the measuring ruler attached to the tank cap as a guide. You can also use a clean funnel to avoid spilling liquid.
5. 5 Wipe off excess liquid and screw the cap back on. Make sure the cover is securely tightened and the rubber gasket is installed correctly.

Tips

• Always use a new, unopened container of brake fluid to prevent moisture from entering the container, as brake fluid is highly hygroscopic.
• If you notice fluid in the passenger compartment behind the clutch pedal, this means that you may have a leak or a malfunction in the clutch master cylinder.
• Wipe off any brake fluid stains immediately with a thick cloth, as this is very corrosive and can damage paintwork or clothing.

Warnings

• Always check your owner's manual for specific instructions and requirements for your vehicle model.
• Do not use DOT5, high performance brake fluid, as it is not compatible with other brake fluids and may damage the brake system if mixed.
