HI,
I have an LSD clutch dual diaphragm pressure plate in my 95 civic. It is a real pita to depress the clutch pedal. I have replaced both the clutch slave and master cylinder, but it still feels very very stiff and rubbery(it rebounds very quickly). Are there any tricks or aftermarket clutch master cylinders to lessen the force required to disengage the clutch?
Thanks

 

Aftermarket master cylinders actually have larger bores, meaning they move more fluid and reduce the throw even further. You want the opposite.

Sadly, the only real solution is to get a different clutch . Dual diaphragm clutches are going to be like that. Very stiff pedal feel, and it also puts a ton of pressure on the crank snout. That leads to a whole host of problems, including destroyed thrust washers. (This is what I've come to understand BTW, I have no first-hand experience with dual diaphragm clutches).

You're right, I did the math and all that a larger master will do is reduce the throw at the expense of an even stiffer pedal. I have also heard about them destroying thrust washers. Maybe I will replace the pp when I have the motor out next. Thanks for the reply!
