Or just for the clutch and brakes calipers when bleeding the system? If I were to just bleed the brakes, would the new fluid eventually mix into the clutch lines?

 

depends; what year is your car?
Late model 05's and later do not have a bleeder on the MC. (US models)

 

Mine is an 04 Canadian model.

If they don't exist on the 05's and later, is there really no use to a master cylinder bleeder?

 

correct, if your car does not have a bleeder (you should be able to tell by visually inspecting the MC), then there's no need for a bleeder.
I figured this out a few weeks ago when I installed new brake lines on my car and I had already ordered speedbleedres.

I popped the hood and to my surprise, NO BLEEDER.
My buddy's '04 RX-8 (which we also installed brake lines on) had a bleeder.

Are you getting ready to do a brake job or just adding the speedbleeders?

 

I am not changing out lines, just planning on bleeding the brake & clutch lines and lubing the sliders.

Still got that extra clutch bleeder? I'll take it if you do.

I was going to change out the lines, did you notice any improvement over the oem lines?

 

Wouldn't the master cylinder get bleeded anyways if I am running new fluid through it towards the brakes?

 

No extra clutch bleeder, sorry Byez! (otherwise I'd send it out to you for free)
I definitely feel a difference in my brakes but I also added new rotors, pads and stainless steel lines all at once so it's tough to say exactly what made the improvement.

you should take a look at Richard Pauls' Master Brake brace, that looks like an amazing upgrade. I didn't realize how much that master cylinder moves around until I was bleeding my brakes. The MC literally dances around as you're just pumping the brakes.

The MC is recommended to be bled when doing fluids but if you don't have a bleeder, you don't need to worry about it. Just put the cap on the MC, (don't tighten it down), bleed all the other points and you'll be fine

 

Thanks

The manual doesn't really mention anything about bleeding the clutch and I can't find much on this site regarding a clutch bleed. Is this something that is really only necessary when doing a stainless clutch line job?
