Clutch seems hard

I've noticed in the past few weeks that my clutch seems like i have to push it fairly hard. not stomp on it but it gives some feed back when i push on it....is there anything i can do to fix it?

Re: Clutch seems hard

like it kicks back at you? Or it seems like theres a big spring pullin it back towards you, Mines always had that hard push but i figured it was just the design of it, my del sol had such a light clutch then when i got my camaro and it was stiff i just figured" ah well it is nearly 20 years old"

Re: Clutch seems hard

A clutch has a big diaphragm spring that "clamps" the clutch disk between the flywheel and the pressure plate to transmit engine torque to the input shaft of the transmission when you let off the pedal. Like a clutch sandwich!

That spring is what you are pushing against (via the clutch pedal and related linkages, all of which multiply the force you are applying to the pedal). Obviously, in order to prevent clutch slippage under heavy loads that spring is a strong one, even in a stock clutch.

Now, if you noticed this difference in effort immediately after the clutch replacement it's possible that your new clutch has a stronger spring in the pressure plate assy. than your old clutch did (a higher performance clutch, for instance, or just a different brand that might have a slightly higher spring pressure). Or it's possible the pressure plate spring in your old clutch was broken or worn out to begin with and not giving as much pressure as it should have, leaving your new clutch feeling "stiff" by comparison, even if it's exactly the same type/brand that you took out.

There can also be problems in the linkage or the throw-out bearing- improperly assembled, worn out, mis-adjusted, binding, etc. Those kind of problems usually feel more "notchy" and involve a loss of smoothness to the stroke of the pedal, not just higher overall pedal effort.

There is no adjustment for the effort required to push the clutch pedal in. You can adjust how far off the floor the pedal must be to fully engage/disengage (with a mechanical clutch linkage), but once you push down to the point that the clutch begins to disengage the effort will be the same from that point on.
