The ULTIMATE Guide to Replacing NA/NB Miata Clutch Slave / Master Cylinders

A complete tutorial on how I replaced my clutch slave and master cylinders on my 1999 NB Miata along with the Flyin Miata stainless steel braided clutch line.
Relatively easy, although a bit fiddly, project that can help if your Miata will not shift easily, especially into 1st or reverse.

i think you meant 2-3 good ugga duggas instead of 12-16ft/lb but it’s okay!

Yes, very helpful vid! PROTIP for Miata Community: After installation of parts and doing the BLEED job...if you have trouble with getting all air bubbles out of line after numerous repeated attempts -- try removing the Bleed Screw and applying a couple of layers of Teflon Plumbers Tape (don't cover bleed hole, though) on threads. After a lot of frustration, this finally eliminated air leaking back into the Slave cylinder (despite the Bleed Screw being fully tightened), facilitating a vacuum for the air bubble-free flow of brake fluid and completion of the Bleeding. Hope this helps others facing this predicament !!

wrap the tape around the bleeder screw and screw it back in? i kinda got the system bled and took it for a drive car was good for 10 minutes and then the fluid got hot/ or an air bubble is in the system which led to the clutch not engaging. i replaced both master and slave

[@FantaconeBoxWorks]

Watched a bunch of videos for this job.... your is probably the best. Simple, no freaking "rave" music and no swearing.

[@KILLERFOX88]

I REALLY appreciate the way you filmed this and did voice over with on screen notations! very helpful and thank you for making it straight forward and to the point

[@Blake240p]

Great video and exactly what I needed to finally fix my NB! I was doubtful I could do this but now I am confident! Thank you

[@speedygarage264]

Glad it helped!

Great video man just bought a low miles NB and two days after driving it home the shifting got more and more crunchy, reverse was basically impossible to get into sometimes. Seems like the slave cylinder died, weirdly there didn’t seem to be any external leaks, I can only imagine there was an internal leak past one of the plungers on either cylinder. Great video man super helpful.

[@dko8546]

Excellent video. Clear instructions and nice camera work. This is the best video I've found on doing the job. Thank you.

[@speedygarage264]

Thank you so much!

I did this last night and used your video. Thank you!

The braided hoses can be a little fragile; I recommend taking a section of vinyl or rubber tubing (ID matching braided hose OD), slitting down its length and zip tying it around the hose. That way, if the hose rubs against anything it'll have to wear through the tubing first.

[@bengerendash]

Did this repair...took about 3 hours. I couldnt get my wheel off though and had to work around it which sucked. The bolts that hold on the slave are quite difficult to get to. Weird angles and very close to the frame.

[@infjcafe]

Super helpful. Thank you!

[@speedygarage264]

I'm glad the video helped yo!

[@bengerendash]

I'm going to be doing this repair in a few days. I was thinking, couldn't you attach the slave to the new line prior to attaching to the tranny and just drop it down through the engine bay to its final location? That way you can make the hydraulic connections before crawling under the car.

A good guide but not the ultimate guide

[@speedygarage264]

I'll take it.

[@yolorl4379]

I did this and it solved my problem getting into gear, but now I have a chirping noise from the slave cylinder that stops when I press the clutch. Can anyone help?

[@danielbartoli7001]

Did you find out what the problem is?

[@steven.ghodgson765]

Very clear video - well done

[@cm2837]

I like the vid, well done.

[@MagicalLisp]

Great video!!!!!!

[@2002MX5]

I have a 2002 NB. Got caught in hour long traffic jam, had to use clutch a lot. I noticed free play of clutch pedal suddenly increased, but didn't affect operation. Once I got out of traffic, the pedal tightened back up. Could this be master cylinder issue?

[@trevorwilson2744]

I had a similar thing happen to me. After getting out of traffic my engine light came on and if I put the car in neutral and let off the clutch it made some small rattling noises. You ever found out your issue?

[@2002MX5]

@@trevorwilson2744 Mine was clutch master cylinder. Yours may be worn clutch. Dunno for sure.

[@Steviedrummerboy]

Great video, much appreciated. Question: Is the new stainless clutch line you installed considered the extended length or the normal length? Thanks

[@speedygarage264]

Hi! It is the extended length one to account for replacing the "pigtail."

[@williamstubbs9737]

Well done! Thanks and a sb

[@speedygarage264]

Glad it helped!

[@rafaelmontoya1454]

Do you need the bleeder system or can you just let it squirt out into a rag or something

[@speedygarage264]

I just use a little catch can. A bleeder system allows you to do it solo, but if you have someone to help you press the clutch, you can just use a rag or old water bottle!

[@stevenhuynh654]

Hi, just got my miata and am having this problem is it because something I did that causes this or overtime? Just bought the car at 165k miles and am new to driving manual.

[@speedygarage264]

Just over time unless you cooked the clutch while learning. But if you just got the car, it's probably something that the previous owner neglected.

[@RemainingCalm]

Thanks!

[@speedygarage264]

No problem!

[@SailingWJ]

Did you have to replace the plunger on the Master Cylinder or are they uniform from one manufacturer to another?

[@speedygarage264]

They are uniform!

[@cherryXcanary]

Very helpful thanks

[@speedygarage264]

Glad it helped!

[@rafaelmontoya1454]

I think you meant treasure coast miata not flyin miata for the line

[@reknstudios1239]

My line wont screw into my master cyl for some reason

[@speedygarage264]

Check that it isn't cross threaded. You may need to purchase a new line if the old one is gunked up.

[@Tintoycar]

What's the cost if you have to do this? We have an NB. Thanx

[@speedygarage264]

It cost me about $50-60 in parts. Less if you don't upgrade to the SS lines.

[@user-pz6bp6sn1n]

What year is your car

[@fuserush3733]

thanks, my nb's clutch pedal has become softer and shifting has become hard (almost impossible at times). Is this a master/slave cylinder issue or a worn out clutch?

[@peakjuggler]

slave cylinder
