I just had the same failure on my 2011 that has 33000 kms on it (20000 miles). I had it towed to a dealer who performed a service as per tsb. They changed the fluid to GTR fluid and said "all is well". It lasted 5 miles. The car is now in Battle Creek Michigan and I am home in Toronto Ontario. I do believe I may have to find a better vehicle.

Master Cylinder has been swapped. Fluid flushed 3 times (why 3, idk, I didnt ask). Still similar symptoms however.

Start the car, clutch goes to about an inch from the floor (fully functional but only an inch or so for the complete press/release). You can pump the clutch and then it functions like it never had an issue. Turn the car off and let sit for a few hours. Get in the car and the clutch is on the floor. Personally I think there is a leak somewhere or whatever adjusts the clutch is derping out.

Grasping at straws till they actually find something...

^^Does the level in the reservoir change at all? If not, then there's likely no leak in the system. Possibly air still trapped or a bad master cylinder.

Hey Joe,
Anything in the works for an aftermarket master? I know you said clearance was an issue as opposed to the z33, but figured I'd ask.

Thanks!

Thanks to Joe @ ZSpeed; Got this part in, installed. All things are live and well now.

Also, not sure how many of you are in SA, Advanced Asian Auto did the work. Good shop.
