I checked the clutch fluid level over the weekend on my 86 and it was empty. I filled it to MAX level and drove it home. I just went to drive it tonight and the pedal started going toward the floor... I thought oh ****, turned it around and ground the **** out of my tranny just to get it back home. I checked the level again and its empty! I knew I should have bled it over the weekend but I didn't have time. I checked it for leaks and everything is dry. How much fluid can the clutch master and slave hold??? Do you think its leaking somewhere else like into where it connects to the release fork (I have no clue here)??? This sucks. Its the one thing I didn't check before buying this piece a couple weeks ago.



Thanks,

chris

Sounds like a leak somewhere, but it wont come out where it meets the release fork for sure. Its either in the clutch master, the slave, or the rubber flex hose that goes to the slave from the firewall.

There really isn't much way for it to get into the release fork area, the slave cylinder is behind the front of the tranny, so it would just leak off the side of the tranny if it were the slave cylinder. It's interesting that you mention it though, cause my 84 is doing a similar thing and I just replaced the slave. My guess was the clutch master cylinder itself. The salve holds hardly any fluid, if you bled it and got fluid out, it's full. Let's face it, it has to be the slave or the master, or one of the lines or a combination there of, there isn't anything else in the system.

I hear ya but I checked for leaks with a flashlight and everything was dry. I'm wondering if it was just that low that when I filled up the reservoir, it took it all in?? I don't know, I'll have to bleed it this weekend and see if I can get any pedal back first.

the master will leak inside the car, get a flashlight and look under the dash. it could also be the ribber hose, they like to split right before the crimped ends



mike

they LOVE to split on the crimped ends https://www.nopistons.com/forums/pub...DIR#>/moon.gif i suggest getting or making a aeroquip (stainless braided) one....i had the same problem on a rainy night far from home and it was a massive air bubble in the system...bleed the system till the clutch fluid res. is to min and fill it up again 2 times. I have seen fluid actually creep around air bubbles in hydraulics....no ****. Do your self a favor and just replace the slave and master cylinders at the same time...and be poor https://www.nopistons.com/forums/pub...#>/biggrin.png

My master cyl was leaking for a while and i couldn't tell cause it leaks right from the clutch

pedal on the carpet but i have black carpeting.

so i would find out when it was empty and my feet were slipping all over the pedals.

The rebuild kit cost mabe like 30 bucks.

I looked under the dash and under the carpet... there are no leaks anywhere, not near the clutch rod to master, nothing... I don't know. The master rebuild kit is $14 and the slave kit is $10 if I need them. I expect stuff like this on a just about 17 year old car with 167K... lol, that's why I bought it for parts, yet I'm driving it still https://www.nopistons.com/forums/pub...#>/biggrin.png

Just to warn, I have heard that rebuilding, no matter how well you do it, won't be as good as getting a new or remanufactured one.

yah, ive rebuilt them, and it lasts a couple of months



mike

my TII the clutch master died. judge ito got me a tokico replacement. looked brand new. might have been rebuilt though. haven't had a problem since!

the tokiko ones are brand new, i think they are the orignial manufacturer too



mike

also, check the slave. Sometimes the fluid will build up in the boot and you wont find the leak. Most of the time its the rubber hose from the master to the slave.

I had the tokico master and slave in my hand. Then I realized the rubber hose was leaking. I guess I should look before I buy stuff. BTW I replaced my master/slave last year and thought they went out again because I got an off brand.

Damn, I still wanna put in the tokico's just so I can say I have em.

have someone press the clutch pedal slowly while you keep adding fluid, with a flashlight in hand, i suspect you will find the leak.

I'm hoping its the hose, I'll find out tomorrow. From the looks of the master, it probably should be replaced regardless. Funny, I can't find any leaks in the clutch hydraulics yet but it looks like the damn brake master is leaking some where the reservoir plugs in. Now I know the brake master was replaced less than 20K ago and it is holding the fluid level... will that pass inspection?? Do I just need to pull the reservoir and install it again with new o rings or whatever?



This keeps getting better and better.........car runs great but I need to stock it with every type of fluid!!!



:bigthumg:

I changed out all the clutch hydraulics on both cars yesterday. It turns out the leak on my 86 was coming from the front of the clutch master where the c clip holds in the piston.... this is one you would never see without removing it. There is a 1 inch gap in the chassis between the engine firewall side and the interior side.



I have to ask about bleeding the clutches now. Haynes says to have assistant press clutch to floor while I watch for bubbles to come out in the container with brake fluid.. with a hose coming from the bleeder screw on the slave. Well, we did this and on the 86, it turned out good with average pedal feel but on the 88, it is hard as hell to push the pedal to the floor.



I used a stainless Mazdatrix hose on the 88 but I'm sure that wouldn't cause the pedal to be this stiff... any ideas?? Am I closing the bleeder screw to soon?

a mityvac-hand vacuum pump with bleeder kit works well or just open bleeder and put your finger over it and get somebody to move pedal in and out. your finger acts as a check valve letting air only out. make sure your slave cyl bolts are tight we had 1 stripped out and helicoiled it. can be done but not easy. pedal will not get harder to mash when its got air in it- will be easy cause theres no resistance. you may have another problem there. oh yea we have put both master and slave in ours and still have origional line still on it. rebuilt kits didnt last long. https://www.nopistons.com/forums/pub...#>/biggrin.png

check under the carpet for leaks bro !!!!!!!!!!!!!!!







johnny

Nothing is leaking now so it doesn't matter.... I'm just trying to get everthing bled right.



Horn, thanks for the bleeding info, I'll do that. And I took your guys advice and went with new units, no rebuild kits.

I'm running out of clutch fluid alot lately! I check my hoses and the slave and rubber springy attachment. I think my master is leaking but I don't know where. I checked under my dash, I didn't notice anything strange. After read all the comments here I'm still stuck. I know that the master was replaced once upon a time. But I don't remember when, I wasn't even driving at that time. Such I just go out and Buy a new one? if so from where?

I got mine on Ebay (imagine that) for around $50. It was a Beck/Arnley. I could wait though since I have 3 cars. If you need it right away, just bite the big one and go to a local parts store. One place online that I use as a "reference" to get pricing before going local is partsamerica.com. I think overall, they have the best prices on auto parts compared to most stores around me.
