clutch pedal is very soft at the top half and stiffer at the bottom half. It used to be stiff all the way I believe. I checked the clutch fluid resevoir and it was empty. I topped it up, let the air bubbles stop coming out, put the cap back on, pumped the clutch pedal a few times, and the clutch pedal still has a distinct half way point at which the pedal pressure gets harder. fluid resevoir now at max and remains there.
I watched the slave cylinder while depressing clutch and it moves steadily as I press the clutch in and let the clutch out, top and bottom half.. Also I can feel the clutch start to disengage the engine as I press the clutch, before it even reaches the stiffer bottom half, so the clutch is definately engaging and disengaging steadily as I press and release the pedal. What could cause the distinct midway difference in pedal pressure? Air bubbles in the system?
A bit of background, 5 years ago and 70,000 km ago I had the clutch replaced with an aftermarket unknown brand (centerforce?). It held great all this time until finally one day it started slipping on a hard pull, and has been slipping ever since. I can still drive around normal, but I have to keep the acceleration down otherwise it will slip at lower rpm's. It actually holds better at higher rpms, and I can just about hold 5 pounds of boost at 6000 rpms. without slipping.
Could my pedal issue be related to the pressure plate? I'm not sure if the pressure plate was replaced at the same time as the clutch work 5 years ago. It could still very well be the original pressure plate. I'm not sure if maybe a couple broken fingers could cause my pedal pressure issues or not.. could this be related to a faulty master or slave cylinder? could this issue somehow prevent my clutch from fully engaging making it slip?
I have already ordered an exedy stage 1 organic clutch kit and fidanza flywheel and new clutch fluid but I'm trying to make sure the clutch is really bad before I dig in.
Let me know your thoughts thank you..
