Hey guys, I'm looking to get some 100% correct information here. I don't need guys replying with a guess or inaccurate info. I did research and I am making a thread based on my findings.
So here's my dilemma: stock KA, factory 5 speed, still has clutch damper.
On my way to school, my clutch had little to no pressure. I was able to get in and out of gears though. I was forced to deal with it to and from school.
As soon as I got home, I checked for leaks, none were found but the master was near empty. I checked the carpet, I checked the slave and master, I even checked the clutch hard line--nothing. However, on the master, the push rod and clevis were the only thing that had any type of fluid on it (not sure if that's normal--I'm leaning towards no). Wanted to see if there was any leaking so I put in some DOT 3 fluid and the pedal regained some feel and still no leaks. And now I'm stumped.
What could be the problem?
What I was thinking of doing was going through the process of elimination starting with the slave/master and even converting to a SS line. But before I even think about purchasing anything I have some questions regarding the research that I've done.
Questions are bolded:
1.) According to this post (http://zilvia.net/f/showpost.php?p=773885&postcount=4) from a very old thread, you're supposed to match both master and slave bore. (Is this true?) According to that post and several others, '91-'94 S13 bore size for the master was 5/8". But on Courtesy Parts and other vendors, they only sell 3/4" and 11/16" bore sized slaves. What combo should I use for my '93 to achieve a stock feel?
2.) I'm partial to Agency Power SS line especially if I kink the hard line, has anybody had any problems of leaking? Any other brands that are reputable and long lasting?
3.) I usually go with OEM/dealership for important parts but I've seen aftermarket stuff like Exedy, Dorman, and FRSport and they're a bit on the budget friendly side, any experience with these brands in terms of master cylinder? Dorman is the closest price to OEM for master that I may just spend the extra >$20 but if it's just as good as OEM then I'll just use it.
4.) Experience using Nabco branded stuff? This may sound stupid but I feel more comfortable about purchasing branded stuff at dealerships than purchasing the same branded stuff from a merchant/vendor. So in this case, I'd rather purchase a Nabco slave from the dealership than a Nabco slave from CP or FRSport.
Anyway, I am stumped and I would like some help from those more knowledgeable than I am. Thank you for your time.
