Clutch Issue

[xALmoN]

Recently, i found that my clutch goes from soft and comfy to suddenly very stiff, it is a very shocking transition, but after pumping a few times, it goes back to soft again.

And occasionally, (more like daily now), when the weather gets pretty hot, i sometimes hear a squeal when depressing the clutch pedal, seems like its coming from the pedal, but then sometimes it seems like its coming from elsewhere, like the squeal only starts when the pedal is fully depressed. It sounds like opening a door with unoiled hinges (i'm hoping that's what it is, unoil pivot ball).

So, i think i've narrowed down to these 3 probable issues.

1. Air bubbles in the system

2. Master Cylinder is kaput (well it was $30)

3. pivot ball needs oiling, or destroyed (gearbox out) =(

How now brown cow? Does somebody want to come drive the car for a bit and tell me the issue? =D

It didn't start till the day of my first paper, on the way to my exams, the clutch suddenly became hard, and then lasted that way till i arrived and parked, no leaking fluid, but the reservoir was low. When i finished the paper, clutch was fine again.

Clutch is an OS giken twin plate,

everything else is stock.

I previously had no pressure in my clutch pedal and had to drive around by turning off the engine, putting it into gear1, then starting the engine to move off, rev matching to change gears. The issue was fixed by changing the vac booster, so if anyone is facing the same prob, try it.

There you go, hope i can have an idea what the issue is with the silly car, and then come back and stamp out all those gremlins.

My first guess would be leak somewhere in the clutch booster system (its looks and works like a brake booster, but smaller)

hmm, where is that booster thingy you talk about?

are you talking about the vac booster? next to the master cylinder? that thing is huge though...

Its a lot smaller than the brake booster, lower down and closer to the transmission tunnel - IIRC its probably about 10cms in diameter and yeah it will have the clutch cylinder attached in much the same way as the brake master is attached to the brake booster. Check the vacuum pipe going to it for leaks.

If what i've said doesnt match up with what you see let me know and i'll go and have another look - the above is all from memory, and i have a crap memory...
