Some clutch problems came up recently. The release point has risen, the pedal feel is awful and driving is now bit annoying. Or difficult.
I’m pretty certain that the master cylinder is ok. When we did the auto gearbox swap with Maladar some time ago, I got a master cylinder repair kit from toyota. Now, afterwards, why o why didnt I check the release cylinder as well. Probably thought that it was ok but never really tested it. What can I say – assumption is the mother of all fuckups.
The problem is bit weird. I do have a ATS carbon clutch with lightened flywheel and everything, but hopefully the problem isnt there. The clutch isnt slipping and the release bearing, the fork that moves the said bearing and everything around there seem to be ok. The release cylinder on the otherhand seems to have some weird kind of pressure build-up. I can push the rod that comes out of the release cylinder all the way back, but some kind of force pushes it back agains the clutch fork. I’m not sure if someone before me has “upgraded” the spring that is inside the release cylinder.
To fix the problem I got a used (found it from a car wrecking site) release cylinder and also bought a repair kit. I found out that the SC and NA versions have different release cylinders (part numbers were 31470-17010 for NA and 31470-17020 for SC) altough the same repair kit applies to both. The main difference seems to be that the clutch pipe seems to attach to the cylinder in different angle. NA has a slightly higher angle than SC. I will post photos when I have both next to each other.
I’ve given some thoughts for a proper flush and bleeding of the clutch line, but the clutch release cylinder seems to move without a hitch when pedal is pressed. I’m bit baffled with the whole thing, but I hope I will get enlightened when I get all the parts.
