Default clutch pedal going soft in 5 mins. not loosing fluid.

I am having problems with my clutch pedal going soft. It started where it would get soft over night and I would just pump it a bunch before I drove it. and now its down to like a few mins. I replaced the slave about 2 years ago. and I was planning on removing the damper.

I dont see a leak though and it doesnt look like I am loosing fluid. I am putting the car in the garage so I can see if it leaks.

any definite if its a line, dampener, or master?

sounds like you need a new master or slave cyclinder. Either way, you should change out both of them

Theres no point in to replace things that arnt broken. thats throwing money at a problem and I don't believe in it.

is there a way to rebuild the master?

I had that problem before.. well VERY VERY similar... it was a pinhole leak in the clutch hose. It didn't really "leak" but would lose pressure... for obvious reasons.

well it wast the master cylinder. and still will be soft if I let the car sit and I dont hit the clutch. I am thinking about doing the slave.

I dont see any leaks and if it is its a slow leak because the master cylinder stays full.

I think its gotta be the slave because you are able to build pressure if you pump the clutch. I am thinking about removing the damper too. but I need to find the fittings.

so I need to find out the fitting pitch. i know its a 12 and a 10mm but what pitch are those.

Don't ghetto rig ****....

You fix the problem the right way, it doesn't happen again. Period.

No there is no available rebuild kits or anything for the master cylinder, because its retarded to rebuild them.

yo man..look at the booster and inside to make sure the master isnt leaking...in addition you could be pulling air into the master...thats what my civic did..i didnt lose any fluid but every now and then it would get soft and sometimes go to the floor...a blown slave will leak everywhere...get someone to pump it while you check the lines also...

First off. I don't "ghetto rig" ****.

Its not "retarded" to rebuild cylinders. brake or other. I was just asking if there was a kit available.

I did fix my problem the "right way" and aparently it wasn't. I replaced my master with a new one and still have a problem. I am doing the slave tonight.

Mgags7/bb4 I know you know your ****. And I respect your advice but that post didnt help a bit besides to put someone down.

SO if its not the slave or the master. its a hard line or that one rubber hose.

if the slave cylinder doesn't cure the problem, you might have a problem with the pressure plate itself

If you have to pump the clutch to get it to feel ok, the problem is hydraulic, not the plate

Now, the fact that you build pressure when you pump it doesn't really isolate the problem. All that says is that there is no really huge leak anywhere, and that the seal on the master cylinder piston is at least somewhat ok

Did you check under the dash (chris there is no booster on the clutch pedal ) where the shaft comes out of the master to see if its wet?? Check the shaft, the carpet, the mat, etc...try to find some wetness....if that is the problem, of course, the master is bad

If that is dry, then move down the line, the next thing to look at is to make sure that the hard line and the connections thereupon are totally dry, if they are, then check out the lines into and out of the dampener....

I suspect these dampeners are going to start failing on our ludes as they all age, I still need to dissect one and figure out how they work, but there are obviously two functionalities.
One, fluid has to flow through it in order to bleed the clutch system.
Two, it has to reduce the force required on the pedal, so in order to multiply the force, there has to be two chambers, the one that the fluid come into first must be bigger, and when you push the clutch, a semi-sealed piston pushes up into a smaller chamber, and displaces less fluid out than came in, that is the only way that the force would be reduced.

This is how I visualize the inside of the dampener, if anyone knows better please correct me....



Anyways, if the seal on that piston in there goes real bad, it may take a while to build up the pressure behind it....hence the extra pumps

But yea after that long *** analysis, the slave cylinder is probably the problem...but who knows...

what happened to madcitylude and that braided ss line??

Well it was the slave. but I replaced the master also and its nicer then ever. I will be removeing the damper if I find the fittings. So did anyone every find the 10mmx1.0 and the other 12mm x something.

is this better? its what I did to my old lude when it hit a telephone pole. drivers door first.
