My clutch pedal has gone/broken, not functioning.

If a hydraulic clutch, the fluid is low or has leaked, leading to air getting in the system. Thus the clutch will not disengage and let go of the gearbox.

If a cable clutch the cable has broken or gone right out of adjustment.

Also check the clutch pedal return spring, as these do break due to wear on the attachment hooks.

your car will need to be diagnosed by a mechanic Tracy. It sounds like the clutch has gone. It might be that your clutch cable or hydraulic actuator might have broken. If the pedal feels different to how it used to it might be the actuator (cable or hydraulic system,) that is cheaper to replace than the entire clutch. If the clutch has gone you are best off replacing the unit as a complete unit, it is tempting to save a few pounds/dollars but this a false economy usually.

Good Luck

Can be broken spring on the cluch pedal in side the car, that hold the pedal all the way back for full amount of brake fluid to the slave cylender, can be checked by pulling the pedal all the way up before steping it to the floor and putting in to gear or just look up under the daschbord on the pedal. Can allso be to little brake fluid in container. To check the master cylender rubber, step on the pedal putt in gear with engine running and wait with pedal all the way to the floor, if the rubber is gone the car wil start to go after some time (1/2-1 min or less) To check the slave cylender rubber will be dune the same way and working same way but it will be leaking out and on the floor.

if its hydraulic then you need to check the fluid level in the clutch master cylinder.if its out of fluid you could have a leak in the system or the clutch has gone bad.(throwout bearing,pressure plate).check to make sure nothing is broken under the dash with the clutch pedal mechanism.if its cable then check the cable for breakage,check to see if the clutch arm it attaches to at the transmission is cracked or broken.just suggestions.

If theres no damage to the clutch pedal assembly, (no bent fork arms or broken springs), then it sounds like the throw out bearing has gone out.

The pedal box supports the brake pedal (& clutch pedal if it is manual transmition), if it is damaged or broken the operation of the pedals will be impaired & the brakes or clutch will not operate properly

There is an assist spring that my have broken, up under the dash, if it is in place and functioning, the clutch itself is the next area to open up.

what do you mean by broken?
Is it;
a) just hitting the floor?
b) is there just no pressure?
c) or has it fallen off?

if its a or b the clutch cable has probably broken. or if the clutch has gone the pedal will feel the same but the car will not move.

The shaft attached to the pedal connects to a device that changes the forward motion of the pedal to a backward motion to the clutch. These shafts are attached with cotter pins and you might be lucky and simply broke one. Check this site for how a clutch works: http://auto.howstuffworks.com/clutch.htm

Reattaching the shafts with new cotter pins isn't hard. But if one is broken, you have to get a replacement. Try a junk yard, it's cheaper.

it sounds like your clutch release bearing has or is colapsing.when you press the clutch the release bearing is under the most load hence the noise.gearbox out i,m afraid.Can you still get gears ok ?.Also the pedal box,s are prone to break on polo,s ,the symptom for that is like a squashy pedal and hard to get gears.if you can look up at the top of the clutch pedal where the cable mounts see if the bracket the cable fits in to is broken away at the top.
