Default Back with old clutch

So at 110K miles I put a monster stage 1 clutch in with a tick master cylinder. At 125K and driving in traffic its wearing my leg out and I want to install the old one back in. My intent is to use the original GM pressure plate, monster flywheel and tick master cylinder. Couple of questions:
1. Is this a bad idea
2. Can I mix and match parts or.
3. Will the monster flywheel work with the GM pressure plate

If you are using a tick 7/8 master, go down to a 3/4 or 11/16. Any 75 series Tilton master will fit the tick block. It will make the clutch much easier to push.

Default changing master

That master is a mother to change. If it comes out, a stock one will replace it.

Don’t be a goofy gus. A $100 Tilton will solve your problem

Are you in stop and go traffic every day?

I got used to this over time as my leg got stronger.

Did you take the clutch petal return spring off, per Tick's instructions? If you still have that on, taking it off might make things better and give you something to try before you make any changes. Once the clutch is in, you get a bit of a rest - but that return spring will press against you all the time.

The clutch could just be worn out. As a clutch wears, the diaphragm spring raises and you lose mechanical advantage, it becomes heavier to push.

How come you cant buy just the stock clutch disc? The disc mfg's claim the pressure plate is self adjusting, thats why they are sold in kits. Not sure if i believe that.

He knows what he is talking about, the 7/8 inch bore in my car is very stiff vs the 3/4 inch bore in my dads car. That 3/4 inch tilton is so easy to press that it has to be equivalent to stock on foot pressure. Both of us are running monster level 3’s.

You can read up on the parts at the manufacturer's website and hunt for a retailer from there: http://tiltonracing.com/product/75-s...cylinder-kits/

Self-adjusting pressure plates adjust with the wear of the clutch disc. If you remove a clutch disc that measures .260" for a new one, it's like you just installed a disc that's .050" too thick. It over compresses the pressure plate. There is a way to reset the pressure plate, however, but it involves a press and a couple of people.

How can smaller be better she said. Math just doesnt work. P=f*a hence if the area a is smaller the pressure P is smaller. Bigger is better, right?

Self adjusting plate attempts to keep the engagement int he same spot as the clutch wears. You lose return pressure, so it very often presents as the pedal not returning to full height. Many clutch "hydraulic" issues are actually misdiagnosed pressure plate issues due tot he self-adjuster

If you're talking about the clutch discs and pressure plate, Smaller clutches tend to have multiple discs for far more area. Math does work

If you're talking about the master cylinder, that's about mechanical advantage. The pounds per square inch to move the pressure plat fingers is the same. A smaller master means the area is smaller, so the square inches is smaller, so the total pounds of force is less, so your leg feels less effort. You make up for it in having to move your leg further to engage and disengage the clutch.

That's also why the 7/8 master is harder to push. you lose that mechanical advantage
