It's the second slave that's begun to rattle its rod on my car. As soon as I touch the boot with my finger it stops. Every time the clutch pedal is up (engaged), in gear or neutral, it will rattle. There's no contact with the fork when clutch is engaged. The only time it doesn't rattle is when it makes contact with the fork upon disengaging or when I adjust the clutch pedal to no free play. Right now there's minimum free play and if I put any less it'll put pressure on the release bearing. Am I doing something wrong? It's the second slave cylinder in a row that's doing that. I've bled the clutch multiple times already and greased the rod up as well. Does anybody have a clue to what should I do? Am I adjusting the pedal wrong?

Mine does it at times, too. I grease it with Lucas Red N Tacky, and that quiets it down for about a year. Less sticky grease does not last as long. That's all I have.

 

But it rattles inside the boot, did you grease it inside?

 

Inside the boot? the boot should be tight up against the rod...and the rod shouldn't be loose in the bore. Usually they rattle at the rod/fork end when the hydraulics allow it to fall back so there isn't any contact.

Does the clutch feel normal? The master might be allowing the rod to bleed back too much. Can you push the rod back in easily in the slave?

 

Yes, when I go under the car while it's running, I can push the rod into the slave easily. Once I do that the rattling stops and I have to pump the pedal to get the pressure back

 

You still have air in it then

 

Damn it. So you're saying there's not enough fluid pressure to keep the rod from moving in the boot?

I've pump bled it from the slave, I just had trouble keeping the hose tight on the bleeder. I should be alright with this method of bleeding though right? 😮

 

You shouldn't be able to easily push it back into the slave that easily. So it is either got air in it still...or the master or slave is leaking..... They can be a huge PIA to bleed sometimes. I have had to pressure bleed mine when it wouldn't bleed properly using the pedal

 

It has to be air because I'm not losing any fluid

 

Buy a pressure bleeder.

What's the difference between pressure bleeder and a vacuum pump bleeder?

 

Vacuum bleeder pull fluid towards each individual line as you hook it up.

A pressure bleeder is hooked to the MC and forces fluid to all orifices at the same time.

I use it and speed bleeders on all four corners then bleed the MC.
