Hey everyone,

Today my clutch started doing this weird thing where some of the time when I go to push it in there is no resistance and it won't shift, but it only does it some of the time. Also a little while ago it started making a clicking noise when I push it in. Today when I took a closer look at it, I saw that there is a hole in the pedal arm that a button goes in and out of, and the clicking noise is made when the button snaps out of the hole, if that makes any sense. Can anyone think of why it might be doing this no resistance thing only some of the time?

It is a 1994 Escort Sedan

Thanks,

Jeff

Check your clutch fluid resevoir, I think its built into the brake resevoir but only the top of it shares fluid. If its low fill it up then have someone keep pressing the pedal while you look for a leak. The Button thing is probably the clutch start switch but I'm not entirely sure, if it is and the car starts its fine.

the "button" you are describing is the clutch slave. it engages the fork which engages the pressure plate and disengages the clutch so you can shift...

The clutch slave is on the transmission. I think you're talking about the clutch master there, sedanman.

I believe my LX does that too, it's just a little rubber pad that wears out and goes into pieces like you said white lightning, it's just metal on metal contact from the clutch petal hitting the floor bump stop. OR to be safe check your brake fluid master cylinder, make sure it's full, if it is good, if not fill it and start looking for leaks, look under by the clutch petal for fluid, look under the battery where the clutch master is located on the outside, look at the flexible rubber hose that goes from the master to the slave on the front of the trans, and lastly look at the slave cylinder that's on the front of the trans by the radiator fan, have someone step on the clutch and make sure that clutch slave cylinder moves a good 2 inches or so at least, if it moves just a tiny bit you have air in your system and it needs to be bleed and of course find the leak, it also could be a brake hose leaking if it's way low on fluid or a rear wheel cylinder.

specifics would be good to know here for sure, like does the ebrake still work good? if it does the rear wheel cylinders are prolly fine because if they are leaking your rear brakes are gonna be all slick with brake fluid.

Could also be that the rubber parts in the master are just worn to the point that they don't always make a good seal and get good pressure only half the time. There was somebody else out here that was describing that same thing and said when they bled the system the fluid came out like jello.
It could happen. If it's not leaky, maybe that's it.
I know what you mean about the switch, mine does that and it most likely doesn't have anything to do with it. I think I wrapped a bunch of black tape around the hole to make it stop.

Thanks guys,

the brake fluid is full...is there a clutch master cylinder that also needs to be checked, or? Also, I have noticed some vibration when braking recently. Not sure if the two things are related. I used tape to cover the hole on the pedal arm, so it isn't clicking anymore. Still doing the no resistance thing sometimes though.

Yes, definetely sounds ike a master or slave issue.

On a side note, I believe I know what you are talking about, when you wrote button that clicks when you depress the clutch pedal.

Do you have cruise control by chance? It is either the mechanism for the cruise control (That disengages cruise when you depress the clutch) or the mechanism that prevents you from starting the car with the clutch engaged. If the mechanism with the 'button' is on top of the clutch, it is for the cruise. If you tape it, it will be fine for now, but the tape will eventually stretch and you'll have to do it again.

Your vibration in the brakes is most likely due to warped rotors and unrelated.

There is a clutch master cylinder, bolted to the firewall directly in front of the clutch pedal. I agree with DangerRanger and others about the clutch master being the problem.

As for the vibration while braking, I don't think they are related. The only thing the clutch and brake systems share is the fluid and the reservoir. I'd check and make sure that all the suspension and brake parts are tight.

Thanks again,

how do I check the clutch master cylinder? Is there some way I can know for sure whether its the master or slave that is the problem? Or should I just go ahead and replace both? Do I have to replace the lines also? Sorry for not being too knowledgeable about this stuff. I suppose I'd have to try and find a leak as well.

Thanks

This is not a definitive check, but usually when the clutch master cylinder fails (or starts to), it will usually leak fluid into the passenger compartment, down the firewall. Pull the carpet back from under the dash, and you should be able to see any signs of leakage.

Someone posted recently that with the engine off, with the clutch depressed, if either master or slave have failed, you would hear noise coming from them from pressure being released from bad seals.

So I replaced both the master and the slave, and the clutch is working fine now...maybe even a little smoother than it was before. I'm not sure if it was the master or the slave causing the problem. Once I had installed them, I was able to fill the system back up alone by manually operating the slave cylinder. Also, I took the fan out (3 small bolts and a clip), which made working on the slave cylinder much easier.

Thanks for the help, everyone.
