Default Clutch Pedal Sticking At High Rpm?

I Have New Tranny, Slave And A 1 Year Old Mcleod Adjustable Master. Running A Twin Disc Mcleod Clutch And At The Track When I'm Jamming Gears, The Pedal Will Stick When Shifting(especially From3rd To 4th). It Only Sticks When I'm Banging Gears. Any Help Is Appreciated.

Have you done the drill mod? I think this is usually the cure for a sticking pedal. Someone else chime in.

There is a link on how to do it on Install University .

My spec clutch would stick at high RPMs after it was worn out. Clutch disc springs fell out when I pulled it.

How many miles on the twin? How hard have you been on it?

I have an 02 car with the Z06 clutch, 01+ slave etc... I performed the drill mod and still had the clutch stick to the floor on the 3-4 shift and you could feel the clutch pedal getting mushy on the 2-3rd shift. I read so many different ways to fix the problem but none worked except for Nine Ball's idea. The braided SS line from the master cylinder to the slave is located very close 1 1/2" to my headers allowing ungodly amounts of heat to hit that line making it extremely hot under WOT. I sliced open a length of 3/8ths fuel line and wrapped it around the braided hose. It seemed to help but the problem was still there. Then I double wrapped the fuel hose over the braided line with 2" wide aluminum tap. Then I fashioned a heat shield out of metal flashing 10" long and used nylon tie wraps to wrap it around the hose where it is close to the header but still allowing enough room for an air space to cool between the line and the header.
I was still skeptical as to if it would help but now after a month and a half I have never had my pedal stick to the floor or had a mushy feeling pedal since I wrapped the line. A huge thanks to Nine Ball!!!!!!! You might also want to try Valvoline Synthetic DOT V fluid also as it has a 500 degree boiling point which is much higher than standard DOT 3. HTH

Before you put a lot of work into trying to fix this, make sure your reservoir is full with clean fluid. I was having this same problem and found my clutch fluid to be very dirty and low. I changed the dirty fluid and filled it to the proper height and the problem has been gone for months now.
