It's not actually freezing, but when the temperature dropped below freezing last night, my clutch started acting as though it needed to be bled severly. I did this, and it work fine for one short drive, then the car sat for about an hour or more. When I came back out, it felt as though it needed bled again.

Long story short, I ended up having to pump my clutch for shifts. I have already rebuilt the slave cylinder, and can see no sign of leakage. What could be wrong?

Also, my idle has been very tempermental in the cold, but that I think I can handle. I had problems Thursday with my idle, and then Friday when I had a chance to really adjust it, I finally got it to idle at about 750-800, for the first time ever. Normally I had to have it above 1k to keep it happy. Then last night when it got really cold again, I had to adjust it over 1k again.

Are problems like these the reason why so many 7s are parked for the winter? I never had problems like this last winter that I recall.

Please help! I am to the point where I think I may need some form of voodoo or something to get this fixed, cause **** just ain't makin any sense.

Thanks,
Brian

rebuld or replace the clutch master and it's hydraulic line. flush fluid with valvoline synthetic brake fluid.

when the clutch slave goes the clutch master is usually not far behind.

OK, so would the temperature change cause the viscosity of the fluid to change? Cause it's my slave cylinder that is leaking again. Or do I just need to repace it instead of rebuilding again? Can I hone it out, and get an oversized o-ring seal? Just throwin out ideas. Let me know, before she becomes a cliff jumper.

I did the hone on mine, and rust formed in the slave in just a few weeks, ,,, but that made the pedal hard to push in,,so i replaced it... sounds like yours is the opposite tho,,,,also i had a pin hole leak in the short hose from the master/slave that made the car want to go forward at long stops,,,like letting the clutch out....loosing pressure,,,so replaced it too,,,,,good luck

BrianHeston

Well, I just realized when talking this over with a friend that I have what should be a perfectly good slave cylinder available to me, just sitting peacefully on our parts car. So that will be going on today, and we'll see what happens.

You loosin clutch fluid?

Check up under your dash where the clutch pedal is mounted... I betcha have a river of fluid pouring down.

i just replaced master and slave last weekend

BrianHeston

Well, I got the spare from the parts car. Looked like **** inside. So I decided to hone the original. I'll put it back on tomorrow and see how it goes. The leak was due to a slightly warped seal that developed a hole, almost more like a tear. So hopefully once I get it all back in place, with the new parts from a rebuild kit, everything will be happy again.

yeah this is all so familar symptoms off a part getting ready to go, my vert did that, and wasnt maybe a week later of sitting it died, i went to start it one day, the clutch felt funny and then drove it a little, then there was no pressure, had to replace the MC and the SC

BrianHeston

So do you guys think that honing and using the rebuild kit is just a waste of time/money? How much are new cylinders? Are there better aftermarket brands, or is OEM the best? And where would be the best place to get them? I'll look around and see what I can find, but some recommendations would be much appreciated.

I tried rebuilding mine, problem remained so I bought a new on $30.00. Got it at local parts store.I have the exact same problem, I'm not losing any fluids but I have to pump to shift. Thinking about replacing th MC but don't want to just throw money at it unless it's gonna fix something. I think the temp affects the seals but am not 100% on that.

Master and Slave clutch cyls are pretty damn cheap, especially compared to alot of the other parts on our cars.

Don't risk it, just grab a new Master, Slave and Hose. Problem solved. (Victoria British, Mazdatrix, Local NAPA store... whatever)

Now that I have a new SC and hose it mUST be the MC, right?

nickj

Replaced the MC this weekend, $60 from Mazdatrix for a new one, and I no longer have to pump the clutch to shift. If the SC leaks, you lose fluid. If the MC leaks, you don't -- the blow-by returns to the reservoir. The symptoms are about the same, otherwise. Cold weather does seem to make things worse, but I can't imagine why.

BrianHeston

Well I got it all put back together, and it feels better than ever. Hopefully it'll stay that way. It even feels better than the last time I rebuilt it. But I didn't hone it that time, and didn't completely change out the fluid either. This time I did both. If anything else goes funny, I'll let you know, otherwise, you can assume that it's all great.

Thanks for the advise and comments guys,
Brian
