Yes, the tube in the jar of old fluid will prevent air being sucked back in to the system.

Thanks, sammm, I tried to find the link, but couldn't. I was counting on someone having it.

I calculated the brake line capacities on the back of an envelope. Being generous, the master cylinder hold 2.6 fl.oz. I do the right rear first, the line hold 4 fl.oz. so I stop after 2 fl. oz. and refill the master cylinder, and bleed another 2 fl. oz. and refill. Next, I do the left rear. From the "y" to the left caliper, the line holds 1.7 fl. oz., refill the master cylinder. Next, I do the right front, 2 fl. oz., refill. And finally, the left front, 1 fl. oz., refill and you are done. I use an old baby bottle to measure.

By doing this, I don't need to jump up and check the level in the master cylinder, I know when to go refill it.

Also, Track Dog Racing has this.

PS: Although you haven't ask, I use Ford High Performance Dot 3 brake fluid. Dry boiling point is 550*F, wet boiling point is 284*F, so I change often. It's also TCB.

^ Now that is some important and true information!!

Lots of good info, thanks to all!! I know all about that brake fluid on paint...not a good thing!! Looks like the brake job is going down Sat morn. I can gather all my supplies on Friday and be ready to go. I've done the brakes on some of my other cars in the past but not the Miata. Seems to be a pretty straight forward job.

Hopefully all will go well and the annoying squeaking will stop!!

Nothing beats a pressure bleeder. I bought a miata motive bleeder and it was the best $60 I had ever spent. I could probably bleed all 4 corners in under 5 minutes!I am out of town this weekend and if you need to borrow the bleeder next week let me know, I live in north Plano by 121 and toll. Lee

I'm a fan of the reverse bleeder when the lines have gone dry or seen air through the master. I made a reverse bleeder out of my broken Motive bleeder because Motive is a liberty hating terrorist and would not sell me a replacement hose.
