New slave and master cylinder /Ford escort gt/ Air in clutch line? Sign In

Earlier in the month.
Put new slave and master cylinder on.(master is dual brake and clutch)
Bench bled the master.
Had son on the brake and clutch pedal.
Started bleeding from the back then the front and clutch last. I had a cLear solid stream no bubbles at all on all fittings. When we were done I had him work the clutch, It engaged and disengaged fine.

Drove the car last week, no problems.

Car sat 4 days, went to drive away today. Started acting up. (Slave) I noticed the old sign of failure. Wouldn't go into gear. Sat and pumped the clutch, went into all gears fine. Drove down the road, stopped and started a few times.

Got back home. Put it in 1st, put brake on and eased out on the clutch. Started to stall. Popped it out of gear. Pumped the clutch. Worked fine.

I've read bad things about new slave cylinders failing. Mine has a one year warranty.

I was anal when we bled the lines. I went back and bled em twice. It's hard to believe I still have air in the clutch line, that's all I can guess what's going on. Keep in mind I drove it last week with no problems at all.

Sure sounds like something is going on with that slave, is it new or rebuilt?. You may wat to check the line, that it is secure to the slave, sounds like air is entering the system from somewhere, if your slave is warranty you may want to try another one. Each time the pedal was soft and it was pumped up did you try to bleed it. That was good that you bench bled the master.

Why are you thinking the brake and clutch are the same master? They are two different ones. Never been a car made with them combined or you'd be locking up the brakes every time you shift gears.

If this worked right as you said before, then you may have gotten a dud part. The Ford clutch systems can be a real pain to properly bleed and get all the air out. Most of us use something to fill it through the bottom like a Phoenix bleeder.

There is no need to bleed brakes when you install new clutch parts. Look for leakage on the clutch hydraulic parts and try bleeding again

This is my first auto that didn't have a separate clutch master cylinder.

News to me! It does share the reservoir with the master! Only real issue is that if either system goes too low you can get air in either.


Keeping it filled enough while bleeding rules that out. If pushing both brake a clutch at same time and bleeding I suppose if you don't do it properly some return air if any could be introduced into the other but really should show up as a problem right away not lots later?


Pic if show of set up if correct at all?>>>>

Have a look at Tom's pic. Your pic is of a brake master cylinder. If that's all you replaced, you have done nothing to your clutch other than bleed it. Think about it, if the brake and clutch used the same master, hitting one would hit the other. Light brake applications would be riding the clutch. Hitting the clutch would slam on the brakes. Your car simply uses one reservoir to feed them both, but they are separate entities.

You need to be working on the clutch master as shown in Tom's pic to have any effect on your clutch. Bleed your brakes and change parts til the cows come home, it won't make a bit of difference until you are actually changing clutch parts.

Nick - Never saw one like that but think it just shares the tank for fluid. It might have a total separator between fluid levels IDK but fill from one instead of two????


Master clutch cylinder shows just a hose to go to a source no tank option. I just can't see why this would be made this way and how one really should effect performance of the other in a failure. More questions than answers as never dealt with this exact deal but would be obvious I think in front of us,

They all have their own reserve compartment so any failure of one will not effect the others.

Problem is not driving down the road. Going down the road it shifts fine.

Problem is sitting idling. And this is intermitten. 1 you can't get it gear. Pump the pedal 3 - 4 times no problem. 2 it's in gear and you feel/hear the RPMs change hard to get out of gear pop it out and it feels like there's no pedal. Pump it 3 - 4 times no problem.

Issue is sitting still idling.

Had my son help me again today. I preasure bled from the slave bleeder valve back to the master. He definitely saw air bubbles come up twice. We bled it a few more times.
This time I used a leak detector on the slave bleeder valve, line fitting going in and the rubber boot. There were no leaks.

Took it for a ride, shifted fine till we got back home and sat with it idling and it did the same thing (intermitten again).

The clutch in it isn't that old. 2 (pro) mechanics put it in.

However the set up works with the master, the brakes work great.

My old toyota has a separate master for brakes and clutch. I can vouch that it's allot easier to work on.

Of course it shifts fine going down the road. You don't even need a clutch f you time it right.

The only thing different about your system is they both get their reserve fluid from the same reservoir. The systems work the same.

You're trying to do something with no equipment that most techs struggle with even having all the best equipment. Take it to a shop.

You sound just like my one mechanic buddy.
He laughs and says your not a mechanic.
Then there's the other one that claims he knows more than 1st one.

We're on here looking for help because we can't afford expensive shop rates or loose our vehicle for a week.

Why do you bother with playing moderator? You don't seem to have patience for us novices. I've read allot of your replies, pretty much your an idiot take it to a mechanic.

Tom is the opposite side, way more patient and helpful. Even if he's not spot on you feel allot better.

Think I'll go to the Ford escort owners site. It's guys that genuinely want to help each other and share knowledge and tips. Ban me if you so desire you ego driven mechanic.

I'd love to perform open heart surgery too. Do you think there is a site that can teach me online?

I just tell it like it is.
