slave cyc. bad ?

The last month or two my car has been gettin harder to shift. somtimes it easily pops into gear other times i can barely get it in, it also ground a little bit today. the last clue i got is that to pedal has like no pressure until half way to floor, and the clutch was replaced last spring. It also seems to help if i pump the clutch. Is the slave cyc. bad or any other ideas thanks

sounds to me like your clutch master is going bad, especially since you have to pump it up. ill bet that the secondary seal in the master is leaking. you wont have any visible leakage though, because the secondary is inside the housing. iirc, the clutch master is about 60 bucks thru nissan.

no visiable leakage, but question is there a master cyc and a slave cyc on the 90 i thought there was just a slave and i was gonna go through autozone since i work there and get one for about $15. Thanks for the quick help

there should be an actuator(slave) on the side of the transmission that connects via a push rod to the throwout bearing arm. it will have a rubber line connected to it. the master will be the one to the left of the brake master cylinder.

Ok went to the car the master clutch cyc is just to right of the brake booster and master cyc. the slave cyc looks orginal would you recomend replaceing both or go with slave cyc first then master. oh i had my dad press the clutch petal very mininal movement from the rod like 1/2 inch

well, when we did mine, there was so much crap in the line from the master being bad, that we just replaced the slave as well. if you can afford it, replace both of them. they probably are both original equipment.

I am gonna try and replace both along with fuel filter and get two tires when i get paid friday. It dosent look like to difficult of a job and tips?

just make sure you properly and completely bleed it. have someone help you do it, its just like bleeding your brakes. this is also a good time for an alcohol flush.

Thanks for the hlep hopfully i didnt damage the tranny of the clutch the clutch would be to major but the tranny would be a pain.

as long as you didnt allow the clutch to slip too much and you werent too hard on it, the clutch and tranny should be fine.

My slave went to crap and hardly leaked any fluid... autozone just acted like the bastards they are and sold me whatever part they thought of without diagnosing the problem. Luckily I bought a rebuild kit instead of the full unit. Cost $16 to rebuild botht eh slave cylinder and the master cylinder.

people who work at autozone sell parts not real mechanics. they dont work on all these cars just hear problems. I got both my parts from there and the car seems to be working good. i am going for a nice drive tonight and i will see how it acts.

the car shifts with pure perfection better then the day i bought it. i think that is the reason he sold this car after having it for so long. it is great now thanks for everyones help

i recently had my clutch not come all of the way up and the next day it wouldn't go into gear! it would just grind. could this be the problem? i was gonna have a shop do a diagnostic and i would fix it because i wasn't sure. my dad left a bucket under the car and when i jacked it down it crushed the bucket. i got a suggestion that it could have harmed the slave but there was no visible damage! any ideas?
