The hydraulic system that actuates the clutch in your manual-transmission car will not last forever. Just like every wear item, the master and slave cylinders will fail eventually. The slave, located near the gearbox, is usually the first to go. Back in the day a clutch cable was the method used, but newer cars utilize a hydraulic system. For old-school enthusiasts like me, the cable-type is preferred. Still, the hydraulic system has its advantages. It will not fail like a snapped cable. There will be warning signs. Here’s what to look out for.
If it is dark and mucky, that’s a sign that it will fail very soon. Now, locate the clutch slave cylinder. This is usually positioned on the bell housing of the gearbox, near the clutch disc, pressure plate, and release bearing.
Be delicate with the metal clutch line and fittings. You don’t want to damage any of the lines. Be prepared to catch any clutch fluid using a bottle of some sort. The fluid is filthy and black. Next, remove the clutch master.
