OK, I keep blowing the slave cylinder and the clutch pedal sinks to the floor when i push it in. the i got an aftermarket clutch is the ACT TY4 hdmm and it has a heavy duty pressure plate and that's what i think it comes down to is that but I also extended the fork more by
welding sum medal to extend it so i can push it out farther cause it wouldn't go in gear before. so this keeps happening so I'm getting tired of it so I'm ready to just change the pressure plate. if anyone can help out or they've had this problem also please let me know Thx.

have you tried changing your master cylinder too? i have a cc stage 5 and the extended pushrod and kept blowing out both cylinders as well. after buying 3 or 4 different aftermarket replacement brands and breaking them all in a matter of weeks, i finally gave in and bought new toyota cylinders from the dealership and they have held up well so far.

yea ive changed master cylinder twice from advanced auto and like 2 3 times from car quest for the slave cylinder. ive extended the the fork that goes to the master clyinder under the clutch pedal but the push rod is still the same on the clutch fork outside on the transmission. hmmmm should i change that pushrod for the extended one also i think they sell one of those dont they.

Glad to see I'm not the only one having this issue, i have replaced master and slave once. now 30k later its doing it again. first time was with the OEM Toyota part, now this time I'm using Doorman manufactured parts. I would suspect there should be
even more people having this problem. We need a stronger master cylinder i know there made for other makes of vehicle that have same type of problems like EVO X. Maybe as a community we can find a solution? I know I don't want to change anymore

I was really hoping considering how many high horse power tC's we have on the forums now that more people would chime in on this subject. Maybe even some of
the shops like PTunning, Dezod or World-Racing would share some insight on this subject. This is the only problem that I've had in 65k miles of boost and abuse on my tC.

i havent checked that could that be the reason why the clutch pedal keeps on falling to the floor i did take it off for me to get to the clutch master cylinder but never checked for leaks when i put it back on.

the ty4-hdmm its a street performance clutch with Capacity: 390 (ft/lbs) Pressure Increase: 32% Over stock its pretty stiff clutch pedal. i want to get this clutch master cylinder to work cause i hate to get rid of this clutch.
