What is the Clutch Fluid all about?
Clutch fluid actually doesn’t exist. Clutch fluid is really just brake fluid that is kept in the clutch master cylinder. When you depress the clutch pedal, this fluid flows from the clutch master cylinder into the slave cylinder. The pressure of the fluid is then used to engage the clutch, which allows you to change gears. After the clutch has been engaged, the clutch pedal will be released, and the fluid will retreat back to the clutch master cylinder.
Keep in mind:
There is no such thing as "clutch fluid;" it is simply brake fluid. It is sometimes called "clutch fluid" because it resides in the clutch master cylinder.
How it's done:
- Inspect the condition of the fluid
- Inspect the clutch hydraulic system for leaks
- Fill the clutch master cylinder with clutch/brake fluid
Your entire clutch system should be inspected carefully during any check-up or servicing. It’s a good idea to have the clutch/brake fluid checked regularly, as it can leak or become contaminated.
What are the common symptoms indicating you may need to replace the clutch fluid?
- Clutch fluid has become contaminated
- A clutch component has been replaced and the fluid leaked out
How important is this service?
Clutch fluid is really just brake fluid, but it plays an important role in the operation of the clutch. The fluid is stored in the clutch master cylinder. When you press the clutch pedal, the fluid moves into the slave cylinder, where the pressure helps move the clutch, which is too heavy to be moved without the added pressure.
If your clutch master cylinder leaks out brake fluid, you won’t have enough pressure to engage the clutch, and your vehicle will not be able to change gears. If the brake fluid in your clutch system becomes contaminated, it can cause severe damage to the slave cylinder and clutch master cylinder.
