ok so i just replaced my clutch last week and was driving home from picking up the wife and lost all clutch pedal pressure at a stop light... replaced the slave cylinder when i replaced the clutch and bearings.. two questions. question 1 is should i have replaced teh master cylinder at the same time? and if so could i just get a rebuild kit for it and do it that way? also how do i konw if its the master cylinder?

 

I always do both pieces since they "see" each other under high pressure...but that's just me.

When you bleed the slave cylinder you made sure you got all the air out of the lines? If there is some air left in the lines sometimes the cluch feels fine. Then gives out later (in my experience , not necessarily the problem, just my imput)
Hopfully something easy

 

You don't necessarily have to replace the master cylinder, 9 out of 10 times its just poorly bled. If you rebleed your clutch and you still feel no pressure from it then you might want to check your slave cylinder, sometimes that can go bad. You want to loosen it up and have someone press the clutch to see if any clutch fluid come out. Good luck!

 

you might want to try adjusting the clutch pedal itself, I replaced my clutch a few weeks ago and it was alright at first then the clutch wouldn't engage. All it took was adjusting the pedal. I mean thats free so it couldn't help to check before you buy any other parts.

 

well i didn't bleed it i went to a shop to get it done sence i didn't have the time to do it myself.. also when this happened i parked it and cheacked the res and there was no fluid in there.... the slave cylinder is new just as a side note. going to be bleeding it though this week and see what happens then..

 

Look on your firewall inside the car underneath the master cylinder. If its wet with fluid from the clutch system, your master is the culprit. Otherwise, fill the reservoir, and have a friend pump the pedal and look for leaks along the lines.

Good luck!

 

My personal opinion is to replace both at the same time. They fail due to age, and they are probably both the same age, so.........
Some guys advocate replacing the hose at the same time, makes sense, but I don't actually do that.
From input from other users, the rebuild kits are NOT the way to go. They end up replacing the whole unit anyway as the rebuild often doesn't work, or fails shortly thereafter.
