The clutch master cylinder generates the hydraulic pressure necessary to operate the clutch by pushing hydraulic fluid through a pipe into the clutch slave cylinder.
Symptoms of Wear or Failure
- Clutch may not work properly, or may not work at all
- Clutch pedal may sink to the floor
- Gears may be hard to shift
- Clutch fluid leak or a need to top off the fluid
Related Repair Advice
- During this replacement, the clutch fluid should be flushed until clean and clear
- On some newer vehicles, the clutch master and slave cylinders, along with the connecting hydraulic line, are combined in a single assembly and not serviced separately
- Vehicles may use a clutch cable or mechanical linkage instead of the master/slave hydraulic system
