    Default Help, ZX2 clutch problem

    Tuesday night at Track Night in America I had a clutch problem. It happened near the end of the third session. When I shifted into 3rd coming out of Wagon Wheel the clutch pedal stayed on the floor. I limped into the paddock. That apparently cooled things down enough that when I pulled the pedal up off the floor, it returned on its own when I pressed it again. After about 30-40 minutes, the clutch seemed normal. So, I headed home and I did not have any problems. Yesterday the clutch seemed normal.

    Does this sound like it's time to replace the clutch master and slave?

    Does anyone have a current discount code for Rock Auto?

    Is the slave line rubber? Old & crunchy?

    The clutch master does not have a reservoir, it shares the brake master cylinder reservoir. There is a rubber line between the two. From the clutch master to the clutch slave there is a hard line.

    A new clutch master cylinder from Rock Auto comes with a new rubber line to go between the two masters.

    PS Thanks for the Rock Auto number.

    C5 Corvettes tend to do that when the clutch fluid gets dirty. Only way I could fix it was with a new slave and new clutch (it needed the clutch). May not apply to you at all.

    Edit
    Try clean fluid to start if it is dirty.

    Other than that, how was your TNIA in the ZX2?

    The two things I really noticed. One, the unexpected grip of the NEW RE71Rs as compared to my 4 year old Toyo RRs. Number two, I really missed the Ultra Shield seat and 5 point harness. I was sliding all over the seat. The gearing in the transmission is a wide ratio and I just didn't seem to have the right gear for pulling out of Wagon Wheel.

    I was still the slowest guy in the intermediate group. I didn't get any clean or nearly clean laps. I was backing off to let someone by all the time. My best lap, on the Race Chrono, was 1:39.76 sec. I forgot to stop the timer after the sessions, so I had one 4 hour long session. I still have a lot to learn about the Race Chrono. At the time trial on Saturday, I'm going to use Track Addict.

    When I get the clutch problem solved, I will most likely track the ZX2 again someday. I sure was glad the clutch came back after it cooled. I was pretty down, with a not working clutch and a long way to get home.

    No. Do you need to have the upgraded version? I just have the free version. And and LG Rebel phone. I'm not sure what version of the OS I am running. I have been chasing other rabbits and haven't done much with RaceChrono or the phone.

    When was the last time you flushed the brakes and clutch?

    It's been so long ago that I don't remember. Which means it could have been last week!

    It's actually been almost three years for the brakes. I was ignorant of the connection between the brakes and clutch, so for the clutch branch of the system, it has been about 14 years.

    Car seems to be doing great now. I replaced the fluid, clutch master and slave. I think it would be evident to anyone that the guy that designed that system knew that neither he, nor any of his friends, would ever have to replace those bitches. I had to remove the air intake so I could get to the bolts that hold the fan so I could remove it, so I could get to the slave. I had to remove the battery and battery tray so I could get to the master. Well the fluid line and ONE of the nuts that holds the master to the fire wall. The other nut is under the dash. I had to remove the drivers seat so I could get under the dash, still could not see that nut. I moved some wiring looms and a plastic junction box, still could not see that damn nut. I had to get a mirror to see the nut. I'm betting it will be a real PITA when I'm 90 years old and have to do this again.

    Again, the car is running hot, straight and normal.
