Clutch fluid is the lifeblood of the clutch system. Without clutch fluid, it will be impossible to engage the clutch and major components of the clutch assembly can be damaged. Over time, clutch fluid can become contaminated or dirty and will need to be replaced.
How this system works:
Clutch fluid is actually brake fluid but without it the clutch would not function. Clutch fluid is stored in the clutch master cylinder and when the clutch pedal is depressed the fluid moves to the slave cylinder where the pressure moves the clutch, which would not move with the increased pressure.
If the master cylinder is low on fluid or there is a leak there will not be enough pressure to engage the clutch. Contaminated fluid can cause damage to both the slave and master cylinder.
Common reasons for this to happen:
Failing External Dust Boot: Clutches have a number of rubber parts that tend to fail. A ruptured or hardened clutch dust boot will allow dirt and moisture to gain access to the cylinder bore outlet and contaminate the fluid. The dust boot should be inspected on a regular basis to ensure that it is not failing.
Failing Seal or Valve: The clutch cylinders have valve seals and if they fail it prevents the master cylinder from raising the proper pressure when the pedal is depressed. Once a seal fails it allows fluid to leak out and contaminates to enter the system.
Clutch Fluid Leak: A leak in the clutch fluid system can lead to contaminated fluid. Water, dirt and even oil can end up in the system. A fluid leak will also make the vehicle hard to shift. The clutch pedal may go all the way down to the floor if the clutch fluid level is low.
Clutch Fluid Needs to be Changed: Like all fluids, over time they pick up contaminants and become dirty. Clutch fluid needs to be replaced on a regular basis, usually at least once a year. If the system is losing clutch fluid on a regular basis the entire system should be inspected for leaks.
Poorly Done Repair: A poorly done clutch repair or service can result in containments such as oil or water entering the system. A professional mechanic should do clutch work.
What to expect:
A top rated mobile mechanic will come to your home or office to determine the source and cause of the Contaminated Clutch Fluid issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
How it's done:
A mechanic will inspect the car's clutch system for evidence of leaks, worn seals and other important components such as the master cylinder for damage requiring repair.
How important is this service?
Dirty or low clutch fluid levels can seriously damage the master and slave cylinders. While adding or changing out the clutch fluid is a fairly inexpensive repair, once the master or slave cylinder is damaged, the repair cost will go up dramatically. Contaminated clutch fluid should be replaced as soon as possible.
