Clutch pedal dropped to the floor. No hydraulic pressure..ive had this issue before and a new slave cylinder fixed it..so i figured thats what is was again..switched it out, got some pressure for a bit, drove it a couple of miles and it dropped again. So i decided to change the master cylinder since ive never changed it and the car had 120k miles on it...again it drove for a few miles and dropped..i decided to re-bleed it with a buddy of mine..finished bleeding and had pressure again but now if i pumped the clutch over and over it would slowly lose pressure and eventually drop. Bled it again 2 more times with the same result. No leaks coming from anything visual.. today i tried again and noticed fluid leaking from the wheel well area, nothing inside the car on the floor mats...its leaking from the back of the drivers side wheel well..where could it be leaking from?...looks like its running into the frame somewhere...brake master cylinder??

Ive changed the master and slave (oem)... stainless upper and lower lines..

evo 9, exedy twin hd, shep tranny

Thanks guys!

 

Either the master, the hydraulic line to the slave, or the supply line from reservoir is leaking if you have fluid back there.

 

Definitely a bad line ._if its the oem hard line replace the entire line with a stm clutch line
