Hi, i have a bit of an issue with my clutch pedal/system, for quite a long time I've had a popping or stiff feeling when operating the clutch pedal, I've had the pedal box off and drilled a 1.5mm hole through the pivot and fitted a grease nipple so i could grease the main pivot as that's where I first thought the problem was, so after lubricating the pivot and the push rod connection under the cover, the noise/feeling is still there, so I checked the flexy pipe and found it was faulty and parts of it were swollen to twice the size it should be, I thought I would improve on the original pipe work and fitted a new braided hose from master to slave, which improved things for a day or two, as the fluid in the reservoir has a grey cloudy look I changed the fluid and I checked it a few days latter and it was cloudy again and the noise feeling is still there I bought a new oem master cylinder which seemed ok at first, been out for a drive today and the noise is back and the fluid is cloudy again, so with my wife operating the pedal I listened with a stethoscope and the noise seems loudest at the slave end, one oem slave cylinder on order, has anyone else had this problem ? what the noise reminds me of is when testing injectors on a hand operated tester, that popping sound/feeling when you over come the pressure to make the injector spray, it's smooth up to the point pressure is felt under foot on the pedal.
