While I'm at it upgrading the braking system, I've decided to do the clutch system also. I've already installed an Exedy OEM clutch kit and resurfaced the stock flywheel along with putting in new seals and bearings and greasing everything up. The parts I'm looking at now are the slave cylinder, lines, and fluid. I do know that they make SS lines, but not sure who you can buy them through. For fluid I'm not really sure what to go with. I will also be buying a speed bleeder for the clutch system also. So, what are my options?

Corksport sells the SS hose.
SpooledupRacing sells the MC/slave cylinders.

I found the SS clutch hose on Mazdatrix and will be ordering it from them. I was wondering about aftermarket master and slave cylinders. My stock ones are working perfectly, but I wasn't sure if they made aftermarket ones. What size Speed Bleeder will I need? Lastly, what should I be using for fluid in the clutch system?

if the stock ones are working fine, why would u need aftermarket ones? you arent going to go any faster for having a different clutch master or slave

Why not replace the Transmission front and rear main seal while its off?

sounds like you have it covered when it comes to clutch hydraulics. I don't know if any replacements for the slave cylinder that are BETTER than stock though. I heard there are good German racing braking fluids (I'll get you the name later) that help with cooling and crap so you can look into those ( you can use DOT3 or DOT4 brake fluid in both brake and clutch hydraulic systems AS FAR AS I KNOW.) I have no idea about speed bleeder systems though.

You could always rebuild the stock master and slave cylinders. They have a kit for both on mazdatrix. New seals are better than 20 year old ones.

bling bling. The bay looks just that much better with it.

Ice_Wolf

I wasn't sure if there were aftermarket ones which functioned better or not. That was my reasoning for possibly replacing my stock ones. I haven't noticed any leaks or problems with my slave or master cylinders yet, but I'm going to have a better look to make sure. I did see those rebuild kits on Mazdatrix and if I do have problems, I will be rebuilding them.

I did replace the front and rear transmission seals while I had it out.

Now that that's covered, anyone know what size the bleeder valve is and any other suggestions on fluid?

rebuilt cylinders aren't recommended. FWIW, all the tuners I've been to all recommend getting them straight from Mazda, I have friends who used discount part retailer rebuilt cylinders and they've had problems up the ****. I don't know how common that is, but that's what I've seen. I'm taking a chance by buying them through mazdatrix, the rebuilt ones they sell aren't official mazda cylinders per se, but they're made by the same company who makes them for mazda.

No-one knows what size the bleeder valve is? What about fluid choices? Thanks for the heads up on the cylinders.

Um, I don't understand what you're trying to accomplish...

Does your clutch hydraulics not respond fast enough?
Is the clutch pedal too soft or vague?

Nothing wrong with stock parts.
I'm ANTI SS clutch flex hose, cause this causes too much stress on the rest of the hydraulics; big, heavy PP's (i.e. ACT Extreme PP) using SS clutch hoses tend to blow out the clutch slave of the clutch master first.

Fluid?
Use whatever brake fluid you're using right now.
Castrol LMA or Valvoline synth in the gold bottle are easy to find.
Why drop big bucks for top-of-the-line Castrol SRF / ATE 200 or Blue / Motul stuff for just the clutch?
Waste of money in my book.
The clutch hydraulics do not get abused (i.e. high heat) like the brakes do.

I believe the clutch bleeder valve is 8mm x 1.00.

Ted, even with brand new master and slave cylinders, you still don't think the SS hose is a good idea?

I bought all three of them to swap out my old hydraulics, so either way it's a done deal already, I just wanted to know your opinion.

why would you need a speed bleeder, get a friend and have them pump, it takes like two minutes to bleed the damn thing

Ice_Wolf

I'm using a stock PP and disc, so I shouldn't have to worry about blowing out hydraulics with a SS line, not to mention my slave and master cylinder are in perfect working condition.

I get what you're saying about the fluid. It doesn't heat up like brake fluid does. I'll be using Ford HD fluid for brake fluid, and will probably use it for the clutch fluid too.

I'll be ordering the 8mm x 1.00 bleeder then for the clutch.

Thanks for the help Ted.

Some of the old TRD Toyota race cars used stock rubber clutch hoses.
They didn't use SS versions cause of reliability.
That made me think...

If it all goes for reliability, then I'm all for it.
The rubber clutch flex hoses expands more than a SS hose.
This slight expansion will help lessen the load on the hydraulic cylinder seals.

IMO, there's no reason to run an SS line unless your clutch doesn't react fast enough...?

My clutch can never react fast enough. =P

Ice_Wolf

That all makes sense too Ted. I haven't heard anything about the SS clutch lines blowing out any of the hydraulics yet. The only thing I've heard about is the SS brake lines failing due to being bad from the factory or not being plastic coated and getting debris into them. Anyone here ever had the SS clutch line fail or have it cause other parts to fail?
