Millenia Master brake cylinder

[WhiteFinish]

He Guys,

Could somebody help me explain what the advantage is of a millenia master brake cilinder ?

I know the Mx3 has a 15/16 and a millenia 1".
But how does it work? Why is it 'better' ?

Thanks.

The Millenia has 2 piston caliper so the volume required to move the pistons in the calipers is greater than our single piston calipers. The Millenia has a larger bore master because, for the same length of stroke, more fluid is moved in the system. Also, because the piston in the master is larger it requires less pedal force to create the same amount of fluid pressure in the hydraulic system.

Putting a Millenia master on a stock MX-3 brake system would shorten the pedal travel and decrease pedal effort slightly. Note however that the ports are on the other side of the unit so some plumbing will be requried.

^^What he said^^

Upgrading the RS to the GS master is WELL worth it, but I cant wait to get the Millenia master installed and tested... it is going to be amazing. The increase should be very noticeable in our light cars. Hmmm Rx7 4 piston calipers, SS lines throughout, and a Millenia 1" master... will make for nice little upgrade from factory, I am deciding now if i want to go with a independent rally style E-brake or just stick with what I got

[mikeinaus]

uhm your planning on fitting rx7 calipers or are already using them? ive never herd of this upgrade before i wonder how much work is involved? probably a tun im guessing...

fyi this mod sounds cool, when are you planning on attempting this josh? do you think this would give similar brake feel to newer cars? ive always found the mx3 brakes to be "squishy" even when properly bled.

[WhiteFinish]

Yes, I'm also wondering how you can do this Josh.

I just sourced some good Mazdaspeed rear calipers and looking for some Millenia fronts (probably gonna get them from thesame car as the Master brake cylinder comes from).

[wytbishop]

The 2 piston swap is much easier with Subaru brakes. The millenia caliper brackets require significant grinding to get them to clear the 323F steering knuckle...which is I assume what you're working with WhiteFinish.

Also...I would say for the record that I've been on the 2 piston subi brakes up front and MSP Miata Sport rears for quite a while now and although it's not like a new car, my MX-3 stops hard and has really good pedal feel.

[Josh]

Did I let the cat out of the bag? ...

well Miata and 323 guys have been doing it for a while. They require a custom bracket which I will make myself out of 1/2 aluminum plate. They can be squeezed in to fit some 15" wheels from what I understand, but I am running 17's so i wont have an issue. Personally if I was going for a clean look I would go with the two piston calipers but I have had these on the shelf for several years now . My only issue right now is deciding on going to 5 lug for bigger disk options, and vented in the rear. I guess I will hit that wall when I get there.

For the squishy brake feel have you upgraded to SS lines? after I did that all of that feeling went away for me, well until the one way valve on the vacuum line for the power assyst failed. I swapped out the crappy inline we have for one from a Honda. was very nice.

I have had my brake upgrade planned for years now and I am just now getting ready to execute it all.

IDK about getting it to feel like a new car, they all have ABS systems that are far advanced over the almost 20 year tech. I personally like not having ABS, It allows me to feel more of the road and what is going on. When I upgraded to the GS master and to rear disk in the MX for ever ago, I was running SS lines and slotted vented rotors and CF hawk pads the car would stop on a dime after the rotors were a little warm. so much so that at 60mph I could stomp on the peddle and lock up all 4 wheels.

I think I found some calipers and brakes on a local junkyard.
- Definitly found some rear calipers M160. Disc size also matches.
* probably only grap the calipers and have to refurbish them since they are in not so good condition
* Need new pads / new discs
* Don't know if the Mx3 brake lines match up ?

- Front calipers found some on a Subaru Impreza '98
* They indicate AD43T on the calipers
--- Damn.. I see that the bolt pattern is different from your picture. Even though they indicate AD43T.
- Some calipers on what we call a Mazda 626 '89
*
* I believe you call it first gen mx6.


Anyways... will just have fun at the JY.

[wytbishop]

The Subaru calipers I used only come on Legacy's. One bolt and one post to pivot on. MX-3 brake lines match right up.

That 626 is the correct car to get the caliper brackets from.

[WhiteFinish]

Oke, got the cylinder

Because it won't be swapped in very soon I'm wondering if it needs some special way to store it?
Are there any rubbers or anything that need to be prevented from drying?


2nd question: Is anybody with a longneck ZE running this MB cilinder? It looks like the reservoir is longer and thus would hit the throttle body. (I haven't checked yet though)

[wytbishop]

I have a straight neck and in order to install that intake manifold at all I had to modify an MX-6 booster to receive the MX-3 GS master cylinder.

You will definitely not be able to do this with the stock MX-3 booster and a straight neck IM.

Any chance you'd have a simple guide for that Charlie? That particular mod is in my near future.

This is the thread where I showed what I did. I had to go find and re-upload the pictures.

That's a great write up Charlie but I have to ask, is this a technical term?

Went to school for 8 years to learn it...so it must be.
