1982 RX7 Manual Clutch Spring?
I have no issues with my clutch, works fine, doesn't slip. But there is no feeling of any pressure when pushing the clutch - miracles of hydraulic mechanical advantage. Isn't there supposed to be a return spring to provide feel to the pedal?
Thanks,
Scott

If he had air in the system the clutch would not work. Lol. The pressure that u feel in the system is from the pressure plate itelf. Probly means time for a new pressure plate. As that means the inadequent force pushing on the clutch disc itself

Guys, his clutch is working/gripping fine. Probably a soft stock pressure plate. Can we trade? My pressure plate is way too heavy for me, even after removing my return spring. Gotta swap to a slightly softer one today to save wear and tear on my left hip. It's like squatting my entire body weight on my left leg every time I press the pedal. No thanks.

But, Yes, sorry took so long to get back. Previous owner put a "new" centerforce clutch in it somewhere around 20K miles ago. Clutch does not slip, function is just fine (usually they slip in 5th gear going up hills when they go bad).
The only issue is that there is virtually no force to push against and I suspect that the return spring provides some of the force - very similar to aircraft when flying hydraulic systems, springs are used to provide feel (unless you are dealing with an older Boeing ).
The hydraulic system is just fine - all replaced when I started this car 4 years ago.
Thanks,

Only springs in the entire clutch system are:
1: Pressure plate
2: clutch hub springs (no effect on pedal feel, and the centerforce might not even have them) and inter-face wave spring (likewise not an issue here, and probably not used on a CF clutch); part of the clutch disk
3: Master and slave cylinder piston return springs (tiny, not really big enough to affect pedal feel)
4: Clutch pedal return spring, which keeps the pedal from flopping around. Likewise pretty small (identical to the one on the brake pedal.)

I noticed a very small difference when I removed my return spring to try to get the darn SS pressure plate to lighten up a little. Then I went with a centerforce and all seems well. Gotta still test drive it after completing the rest of the swap... once it stops raining.

I've driven a TII with an upgraded stage 2 clutch and hated the amount of pressure it took to depress the pedal. In the widebody I have a stage 3 ceramic/Kevlar clutch that's just a hair stiffer than stock, love it.
The amount of pedal pressure is determined by the stiffness of the pressure plate. Organic clutch discs require more clamping force from the pressure plate than the type I have. Mine was 300 on eBay, billy was selling the same one for 400. It's one of the best clutches I've ever owned, including the 11" Schieffer I had in my Road Runner many many years ago.
