Bad clutch master cylinder? Or slave cylinder?
 
Hey guys,

Lately I've been barely driving my car. It's been sitting in the driveway a lot over the past three months. About a week ago my clutch pedal started feeling very slippery, almost as if I had rain water on the bottom of my shoes from wet weather. The clutch pedal feels soft when pushed in, and my brake pedal definitely feels softer too (that might be because I asked the shop to top off the brake fluid reservoir when I got two new tires since I knew my brake fluid was low because of the leak.)

I can still upshift/downshift perfectly fine. My transmission has no problem engaging gears, and the clutch is definitely not slipping. I looked under my car at the bellhousing, there isn't any signs of a leak. The pedal only starts to feel wet after driving around for 10mins after it's warmed up, and there's never a puddle of brake fluid on the carpet. I think I've narrowed it down to the clutch master cylinder going bad, but I just wanted everyone's thoughts/opinions. Does it sound like the CMC, or a slave cylinder? Does anyone know by chanced what the procedure for replacing a CMC is? I.E. How long does the whole job take?

I think I'm going to order this CMC from RockAuto on Tuesday.. let me know what you think about it.

Your on the right track, if your pedal is wet it's from the brake fluid leaking onto it.

Awesome, so it definitely sounds like the CMC and not the slave then, right? Would the loss in brake fluid also cause my brake pedal to go soft like the clutch pedal? I feel like it would since they share the same reservoir..

It could if you lost enough fluid, but I think they have a divider wall in them but I'm not 100% on that.

Thanks, and I hope it goes easy for you. I removed my drivers seat when I did mine so I could have some room to work and lay on the floor.

I ordered my clutch master cylinder from Advance I got it the next day in the morning and by the afternoon it was installed. No more wet pedal :)

I was able to get my master cylinder cheaper at Orielly's when I factored in shipping costs. Normally though I buy stuff through RockAuto.

Bleeding the master cylinder can be a pain. See my write up on the pressure method I used.
