Tarox 10 pot caliper kit?
Discussion
Hi guys,
I just bought myself a 1997 1.8 NA8 that has had the Tarox 10 pot brake kit fitted to it by a previous owner. The kit has calipers, monster sized discs and braided hoses.
Is anyone else running this kit?
I have a bit of a problem in that I can't get the brake pedal feel to be any better than mushy and lacking in feel.
I am thinking that the calipers are beyond the capacity of the stock master cylinder and its ability to move enough fluid...is there a bolt on item available that would remedy this?
I have tried contacting Tarox to see if they recommend a larger master cylinder but they have been of no help.

Assuming its not running slicks, downforce and a ridiculous amount of power, why on earth would you need brakes like that on an MX5?
NFI..I'm guessing whoever fitted them thought they looked good or bigger = better.Its a quick, well modified car set up for trackdays and the like. Around 215BHP at the wheels, LSD, Coilovers etc etc. It came with a 2nd set of rims fitted with A032R semis.
I want to see what these brakes are like when they are set up properly but I don't know if they will stay on the car. They might actually be to difficult to use on track, I have only just bought the car so the other night I found a quiet stretch of road to try an emergency stop and locked the brakes solid almost instantly.

10 pot?!!?!
I want pics!
I bet that looks absolutely awesome beyond belief
I love huge brakes peeking out from inside wheels.
As said above though, totally, ridiculously, comically unnecessary

I think you're spot on.
I'd have thought Tarox would have MC size requirements in their catalogue.
Jibberingloon on Nutz is running the 6 pots IIRC and has effectively removed the brake bias to try to balance them with the rears.
Yes the balance is something else to think about. Am I just going to end up chasing brake problems around and around until I'm sort of happy?!?!I'd have thought Tarox would have MC size requirements in their catalogue.

The Tarox website is pretty useless, their PDF catalogues do not work so I can't see if there is a recommendation to fit a master cylinder. I had some very brief contact with their help center but they have stopped responding to me.

Have you tried the obvious thing i.e. replacing the brake fluid?
With those brakes I'd guess the hoses have been upgraded but are they in good condition?
Have the rear brakes/hoses been upgraded too?
Have you checked the master & slave cylinders for leaks?
Yep the brakes have been completely flushed, a fair bit of air came out of the rear calipers. Feel improved a little bit but they are still mushy.With those brakes I'd guess the hoses have been upgraded but are they in good condition?

Front hoses are braided and in good condition. The rear hoses are the original rubber but are in good condition.
The brake calipers do not appear to have any leaks. There are no outward leaks from the master cylinder and it holds brake pressure...I.E. if you pump up the brakes and then hold the pedal hard there is no gradual sinking.
This is all what leads me to thinking the only way to get them working well is with a master cylinder...I would have thought that with the MX5 being so popular someone must be making a bolt on upgrade?!

Another option would be to remove it all and replace with the standard big brakes from a Mk2.5 Sport. They are plenty good enough for track use and would cost you less than you'd get by selling what you have.
I was starting to swing that way. I don't think anyone else in the world uses the same brakes as me!!There must be a fair weight in them to.
IIRC The Sport has a slightly larger MC - I've converted a few cars to Sport brakes (including mine) and never bothered upgrading the MC as its not needed.
HOWEVER its not 100% bolt on as the pipes are different (IIRC).
Also its not much larger - the reason there isn't a simple answer is that not many upgrade past the Sport spec really.
You are into the realms of Race / Rally cars hence buying Wilwood etc components.
But yes I'd simply sell them on and have 1.8 or a Sport kit.

Hmmm I have found this kit... http://949racing.com/miata-wilwood-master-cylinder...
I still think you don't need those brakes. You'll be better of in pretty much every way with a standard Mk2.5 Sport setup.
They will be lighter, cheaper for pads, easier to service, won't require replacement master cylinder and will still be plenty powerful enough for your needs. You also won't have to worry about brake bias having stock rear brakes (sounds like an odd setup - 10 pot at the front and stock rear
).
My car has more power than yours and Sport brakes with stock discs and Axxis Ultimate pads are more than enough for track use and well over the top on the road.

James I want to catch up soon and have a look at this beast 
I went through many iterations of brakes on the race car, might be able to help you sort it out... I tend to agree that the brakes are overkill, but if they don't weigh too much more and you can get the feel sorted out, might be worth at least trying seeing as they are already fitted?
Do they have a booster fitted?
Have you priced pads for them?

No idea about the MX5 but I did run tarox 10 pots on my R33 GTR. If you drop them an email they're actually pretty good to deal with despite the rubbish web based assistance.
I'd say almost without a doubt you're going to need a bigger master cylinder, and I've no idea what you can graft on to the MX5, but I'd expect you shouldn't have too much bother. There's always places like hi-spec churning them out too.

Hi Tim, What are your plans for this long weekend? I'll send you a message or something.I went through many iterations of brakes on the race car, might be able to help you sort it out...

They can't weight toooo much. I believe they are of billet aluminium construction but the discs are steel, 2 piece items so they must carry a bit of weight.
Yep it has a booster fitted.
Pads are sorted, the bloke that supplied pads for my WRX came through for me and found that EBC do Tarox pattern pads, from their part number / specs he has been able to find a number of different options for me.
Because I use him all the time he is supplying me normal road pads for $100 and can remanufacture the old pads with a track compound for $180. When I send him the old pads he is going to cut another set of backing plates to hold on to so he can get me a fast turnaround in the future.
I agree that it would be good to spend a bit of time fiddling with them, if all it takes is a new master cylinder and a different compound pad to sort then we are laughing. If that doesnt work then I can pull it all off and sell it. The kit is not specific to the MX5 so anyone could use them with new caliper brackets and disc centres. To land a kit in Aus now is around the $3000 mark so I'm sure I could shift them at the right price!

I found there is a one inch bolt on kit available from the states manufactured by Wilwood. Pretty cheap to!I'd say almost without a doubt you're going to need a bigger master cylinder, and I've no idea what you can graft on to the MX5, but I'd expect you shouldn't have too much bother.

I emailed Tarox through their website and had a reply almost instantly which I responded to but they have gone silent since then
Thanks for your help everyone, very much appreciate it!
Bump..
A bit of an update to this thread. I hate when tech threads get left with no resolution!!
I ordered the Wilwood 1 inch master cylinder kit from 949racing a good few months back and finally managed to get it fitted last week.
Well what a difference!! Pedal is hard and takes a nice firm pressure to use. I start to get braking happening right at the top of the pedal and then I can press harder and only get a couple of inches of pedal movement with progressively harder braking effect....sounds silly but the more I press the pedal the harder it brakes. I can modulate the pressure much more accurately now. Before the MC was fitted the pedal would sink at least half way to the floor with no feel at all and the brakes would snatch and lock all to easily.
Something else was sorted with this MC to. With the stock one fitted I would apply the brakes 3 or 4 times and each time the pedal would get harder but then if the brakes were not used for a short period the pedal would go soft again.
I will reserve my opinion of 949Racing for PM's.
