Why is my clutch master cylinder not pumping fluid?
If there are no fluid leaks at the master cylinder, no swirl or bubbles in the clutch reservoir, and the clutch pedal does not slowly descend with constant pressure, then the master cylinder is likely working properly. If there is still softness in the clutch pedal, you likely need to bleed it again.
Why is my clutch not engaging?
A clutch that doesn’t engage fully, or slips under heavy load, is the normal failure mode of a worn out friction disc of pressure plate that has lost its tension. The sudden onset of a slipping clutch usually indicates that an oil leak, or something else has contaminated the friction surfaces.
Why does my clutch pedal go all the way to the floor?

How to troubleshoot a leaking clutch master cylinder?
Start with some basic tests/troubleshooting. Verify that your clutch master cylinder (located driver’s side under the dash usually mounting against the clutch pedal) is not leaking. Verify that your clutch slave cylinder (it will be mounted on the transmission) is not leaking. Verify all lines between are not leaking.
Where is the bleeder screw on a clutch cylinder?
Locate the bleeder screw on the slave cylinder. Attach an appropriately sized tube to the bleed screw to redirect the hydraulic fluid so it doesn’t spray everywhere. This can be fed into a bucket, empty bottle, or whatever. Open the bleeder screw on the slave cylinder.
