s_tubb23 Posted November 28, 2014 Share Posted November 28, 2014 Hi Guys, Started doing some work on the new car I picked up and I've ran into an issue whilst bleeding the clutch. The car is 93 JDM WRX and when I had it the clutch bite was almost on the floor and I was getting the odd crunch on gear change so thought I'd start by changing the fluid to see if it helped. My master cylinder doesn't have a bleed nipple(or doesn't appear to have one) so I've bled the system from the slave cylinder. I've bled the system by having a bleeding kit connected to the nipple, loosening the bolt a bit and having someone press the clutch down, then tighten the bolt and have them pull the clutch up. Repeated this process and topped up fluid in master until the fluid coming through the pipe was nice and clean and as far as I can tell there is no air bubbles. Now for the problem. The clutch peddle does not return all the way to the top like it used to. Instead it pops back up about a third of the way maybe a little less and then you can bring the peddle up all the way manually but doing this there is a very much mechanical clunk. When then putting the clutch peddal down, it drops instantly with another mechanical clunk to the third of the way down point and then it feels like a "normal" clutch again with hydraulic feel. I think the clutch is working in the bottom part as with the clutch fully down I can change between gears smoothly (with engine off due to alarm(another issue but one at a time)) but I need to get the 2/3rds part of the clutch with no feel sorted. Is this down to a faulty master cylinder or does the pedal need adjusting where it connects to the cylinder linkage? Is it more simple then that and I have indeed got air in the system? Apologies if this a simple issue or repeated question - I'm a noob I will admit it but I'm trying to learn by getting my hands dirty. Thanks in advance.
