Place the other end in an empty water bottle and top off the master cylinder with brake fluid. Pump the clutch pedal – If you have a friend with you, have them get in the driver’s seat and pump the clutch pedal 10 to 15 times to build pressure. Then have them press and hold the clutch pedal completely down.
The bite point is usually around half way through the clutches working travel (around mid-way from fully pressed to fully released). The does however vary a little from car to car. An experienced driver will have little need to use the bite point except for very slow moving traffic and moving off on a hill.
Most brake and clutch pedals should have just a little bit of free play, usually about a centimeter, which is less than half an inch. If you feel that your free play is more generous than this, or that you don’t have any at all, you’ll need to adjust your pedals.

Broken Clutch Cable: The most common reason to have a clutch pedal that goes all the way to the floor is a broken clutch cable. This is extremely common, particularly on older cars. … Low Fluid: If you have a hydraulic clutch, there are a couple of other things it could be. One is low fluid in the master/slave cylinder.
When a master clutch cylinder goes bad, the clutch pedal will fall to the floor when pressed and will not rise again. When this happens, the driver will be unable to shift the car into any gear. The vehicle will not be drivable until the master clutch cylinder is replaced.
If you need to pump your clutch to make it work properly then you have a problem (almost 100% certain) with either air in the line OR you have a slave cylinder on the way out. It is not a transmission fluid related problem, as they are two separate systems and completely sealed away from each other.
How to Change a Brake Master Cylinder Without Bleeding the Entire Brake System. The brake master cylinder provides hydraulic pressure for the entire braking system. … When the master cylinder requires replacement, it must be removed from the vehicle, which means the brake lines must be disconnected from it.

This situation is usually a failure of either the clutch master or slave cylinder – they simply wear out. … If the fluid loss is on the ground, under the rear of the engine, the slave cylinder is the failing component.
SPONGY CLUTCH PEDAL
If your clutch pedal feels soft or ‘spongy’ at any point as you press it to the floor, it’s a sign your clutch fluid is low. That spongy, inconsistent feeling is due to air in the clutch line from the master cylinder to the slave cylinder.
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.
Air is sucked into the clutch slave cylinder, thru the cup seal. I know it sounds hard to believe, but the cup’s lip faces inward only with every slave cylinder I’ve been inside. The explanation I remember was that it is most likely to occur when the clutch pedal is fully depressed, and then released quickly.

On a flat road, when moving off, your gas is around 1500rpm on the rev counter; on a hill start you should aim for around 2000rpm. When you move the car off it must work harder to pick up momentum and you may need to release the clutch from the biting point area slower than normal to avoid stalling.
Your clutch pedal should move down three-quarters of an inch to 1 inch without effort and then require a good deal more effort to travel the rest of the way down to the floor. This pedal free-play ensures that when you release the pedal, the clutch disk is fully engaged.
To work correctly, the clutch needs the right amount of freeplay in the linkage between the foot pedal and the clutch operating lever. If the amount of freeplay or clearance is low, it results in a slipping clutch. If there is too much freeplay, the clutch may be dragging.
