What Is a Clutch Hydraulic System (Master & Slave Cylinder)?
Your clutch pedal works through hydraulics. A Cranbourne West specialist explains.
What it is & what it does
On most modern manuals, pressing the clutch pedal pushes fluid through a master cylinder to a slave cylinder, which disengages the clutch. It’s like the brake system but for the clutch.
When it works, the clutch disengages cleanly for smooth gear changes.
Signs of trouble & how we help
A leaking or failing master/slave cylinder causes a clutch pedal that goes soft, sinks, or won’t fully disengage the clutch — leading to crunching gears or being unable to select gear. Low clutch fluid is a warning.
We test the clutch hydraulics and replace the faulty cylinder, then bleed the system for a firm pedal.
