300 Miles On New Clutch, Now Have A Light Pedal

[dancn]

Why would a clutch pedal become lighter after 300 miles on a new clutch kit.

R33 GTS 2.5t, push type

Here’s my ongoing clutch saga>>

My GTS-t was bought with a slipping clutch; i fitted a standard exedy replacement. I noticed 2 things immediately after fitting the new kit. 1. my pedal was much lighter, index finger could fully depress it to the floor

2. At first I thought it was wheelspin over bumps, but it was slippage, not there for a few days, then returned again until I finally pulled the kit out again, and fitted a GTR push type kit.

There is no preload from the slave onto the fork, I can easily push the cylinder away from the fork recess at rest.

After fitting the GTR kit, my pedal pressure was restored and much like before, there was no slippage noticed at first, but I drove the car to work one day (40miles, cruising), and that evening on the way home the slipping started again. It was noticed first under light midrange throttle, and the pedal pressure was light like before.

There is no contamination of the friction plate, gearchanges are smooth and not notchy.

Anyone help with his one, has my pressure plate lost it’s clamping pressure? Hence the light pedal, or is there something else?
