Need help diagnosing a problem with my clutch

your reservoir should be on your firewall, check if it's low would be the first thing, you'll probably have to bleed it if it has an airlock.

best to check that for leaks before you do anything else, it's pretty much gonna be that..

that certainly narrows it down

That reeks of a fluid leak in the clutch hydraulics. As has been pointed out, check the clutch reservoir. If it's empty, odds are you had a leak and it dumped all the fluid out.

Just hope it isn't like mine, where it's a "sealed assembly" and almost impossible to do anything with.

That sounds horrible. All five cars I've owned with hydraulic clutches have developed a leak at some point. It's unconscionable to design a sealed clutch.

OP simply needs to bleed the clutch at the slave cylinder. Of course, you can just pump the hell out of it when you have a slow leak at the slave. That's all I did for my old Nissan pickup for years. I'd just top up the reservoir every 3 months after it went flat, and pump it back up.

What they have said. I have worked on a lot of hyd in my life and it tends to leak in the cold. The system should be able to bleed itself fine after several goes at the clutch pedal though

Sure the clutch plate hasn't rusted onto the flywheel? That's really common after it's been standing.

Rocking it violently back and forth can free it.

I thought that made it almost impossible to push in the clutch pedal - not make it flop loosely.

Im not OP but have a Clutch question too.
I have a 99 s10.

Occasionally, when the clutch is fully depressed it will grind and clunk when I put it into 1st or reverse.
Its just makes noise, it doesnt actually catch hard enough to jerk the vehicle.

My clutch engagement point is halfway through the long pedal stroke, its always fully depressed. Its not like I have a pedal with a really short stroke and im not depressing all the way. Happens randomly maybe once a week or so.

I only know how to change my oil/spark plugs and stuff, never really looked into much else. Where should I start to look?

Well if you see the slave on the transmission then look around it for a bleeder. Open the said bleeder and keep it open till liquid gets out. You prolly have some air in. If you do this and the clutch is still soft, get the master out, you prolly have worn gaskets inside and they let the fluid pass them. They are easy to change usually.

Usually when the transmission cranks when you put it in 1st or reverse it means you have a bad pressure plate. Or it may be some hydraulic problems. It depends on your car. Im not familiar with american cars so i cannot say for sure for your model.

Nopeydopey.
My ducato no. 2 stands most of the time. If it goes into gear but the clutch doesn't release you need to start it with the first gear so that it starts moving. They you just keep the clutch depressed and try to loosen it by braking. The engine might stall several times and you need a downward slope so that you won't fuck up your battery and/or starter. Usually the clutch breaks loose. Then you need to slip the clutch to "sand" away the rust. And drive it more often. It keeps the clutch in a better condition....

>>1139710
and during this time how does the clutch pedal feel compared to when it's operating normally?

>>1139519
Look for fluid on the inside of your firewall may have to look under the carpet behind the clutch pedal

>>1139684
Listen to this guy, OP. A bad seal doesn't always mean external leaks like some posters are suggesting.

>>1139725
It feels normal. It's a 91 ducato (talento = RV).

>There is no resistance in the clutch pedal whatsoever.

yep. sounds like the same problem to me

This sounds like a hydraulic leak. At least you've access to the slave cylinder and maybe a bleed nipple. My slave cylinder is inside the housing of the gearbox near the thrust bearing and requires disassembly to access. All I'd be able to do is check levels, check hoses, check and bleed at the master cylinder and hope for the best. A really common failure on my particular car is for the gaskets to fail on the secondary cylinder and for it to start weeping fluid, though usually this is a gradual failure identified by constant slow fluid loss rather than complete failure of the clutch.

The car should still start in neutral even if the clutch is seized Are you able to manually shift the gearbox? On my car you can actuate the selector forks manually.

rodents have eaten through your clutch hose.

>>1139519
Specify your truck brand/type/year specifications first. check the clutch fluid. Can't do much without the info mate.

You are aware that these are comments from two different people? You are, aren't you?

>You are aware that these are comments from two different people? You are, aren't you?

Does it really matter?
They are both suggesting a rust-frozen clutch is OP's problem when the symptom is entirely different.

>>1139519
Likely a failed seal in the slave cylinder. Unscrew it from the bellhousing and have an accomplice depress the clutch pedal while you watch for fluid spraying out.
