Most guys seem to have bought their Traqmates from Puresport:

I don't really know much about them except that they are pretty responsive to emails.

[STIgma]

Pffft, brakes are for pansies. What you need is more power.

Right, weasel Dave?

[Cap'n Pete]

Yeah, 'cause more power solves everything!!! :rolleyes: :p :D

[shawn cormier]

I think somebody had a Track-mate for sale in our classifieds.

[shawn cormier]

to late.....

MORE POWER!!!!!!!!!!!!!!

[ADAM]

well GPS data confirmed my brakes suck!!!

so..... now we need... MORE BRAKING!!!


MORE POWER is always good as well :)

That was exactly the thought I had when I saw you had the same old Z32 brakes! :eek:

[ADAM]

yeah they suck...

i have to pump them up before every corner which is not a quick way to drive..

time for some serious brakes..since they are free pips anyway

Why the change of heart on brakes Adam?

It sounds like you've already got a lot of work into your current system.

[ADAM]

they just dont have the braking capacity anymore that I need...they are tiny setup vs the speeds that the car is travelling now..

time to upgrade :)

Click Here (http://evolution.skf.com/zino.aspx?articleID=15103) for a brief article on knock back. This tells me that new calipers are not going to solve the issue... unless they pressurize the lines and force the pads back on.

Anybody ever heard of a 1-2psi line pressurizing check valve? I know I read about it years ago and didn't quite know why it existed... assumed it was to keep heat in racing pads, but 1psi wouldn't do that...

[Andy]

Adam, order knock back springs when you order your calipers. Most manufacturers can supply springs with their calipers. We have been using knock back springs on the race cars for a long time.

Andy

[MazdaMatt]

Adam, if your current calipers had springs, would your brakes be sufficient?

[Slowpoke]

... and I would use at least 7lb springs if you're going that route. And no, they don't make up for tiny, insufficient ball bearings, but they help a bit.

[ADAM]

yeah they might be ok with springs? how would I add them to a stock brake setup? where can I just buy these springs? where do they exactly go?





I need to boost them again...pedal effort is too high when I really need to haul the car down...

will modify the brakes this winter and see how it works next season..

[Slowpoke]

Ideally you would machine an inset for the ring in the caliper housing and on the back of the caliper piston. Terry at www.KVRPerformance.com provides this service and you could source the springs through him if you prefer to do it yourself.

He could also counsel some suggestions on reducing your pedal effort.

[ADAM]

Terry at KVR rocks!!!

had a long talk with him..and he gave me 3 options... help me decide..

1= ship my 4 pot 300zx brake sto him, and he can install knockback springs plus caliper rebuild for $400

2=he ships me skyline brakes and rotors with knockback springs rotors are slightly bigger for $850

3=I buy a set of AP racing calipers and rotors for $2850.00 comes already with knockback springs and rotors and race pads and fluid.. just bolt them on

hmmm

I like the $400 option...but maybe I should stop screwing around and just get the AP racing ones?

anyone used AP racing system?

I saw a pretty baller AP racing setup on Dave Pratte's G35 coupe....

[Guillermo]

Adam,
Why have you decided to get a traqmate gps system?

[minispeed]

Not knowing what knockback was I came across the following article that may be of interest:

http://www.stoptech.com/tech_info/wp_knockback.shtml

[Slowpoke]

AP Racing systems are sweet, but I haven't gone there yet. I seriously considered a smaller 15" wheel compatible AP set so that I could slap some rally wheels over them.

I personally wouldn't just add knockback springs. That's a lot of horsepower that you have there to dissipate. I'd eliminate the $400 option from your list. Skyline and AP Racing are the two options that I'd consider based on budget.

What pads are you currently using?

[ADAM]

I am not having any fading issues with the current brakes..I am using ht-10 pads...


G.. decided to go with the trackmate cause the computer interface is great..vs G2x sucks for interface..

Adam

[68vette]

G2X is a nice set up but the interface is not quite as friendly as the Traqmates.
Traqmates strength is it's easy to use software.

[68vette]

Emailing your track files to fellow competitors to compare stats with is also a cool option I like very much. The virtual races are fun to watch.

[Dave]

Adam, how much bigger are the Skyline rotors? Are these OE Skyline rotors or KVR/aftermarket rotors in a Skyline fitment/size? OE rotors don't tend to have curved internal vanes that help pump air thru the rotors, whereas the better aftermarket ones do.

But if you're not getting brake fade from the rotors and pads being overheated, then you don't necessarily need to go bigger. With my G35, after just 2-3 laps around TMP my rotor temps were over 1000 F and the brake fade was so bad that continuing to lap was impossible. With the big AP's I put on it, rotor temps dropped by 50% and I could brake deeper and harder with total confidence, and as a result lap times dropped by 2.5 seconds to a 1:23.7 on street tires. But we're talking about a 3500 lbs car here, and one equipped with an undersized system from the factory (Infiniti clearly didn't expect too many owners to beat on these cars at a brake-torturing track like TMP).

I'm surprised you haven't overwhelmed the ability of the fairly small 300ZX rotors to absorb and dissipate heat, but if you're not having brake fade, then all you really need to fix is your knockback problem. No point in adding unsprung and rotating mass if you don't have to.

That being said, what you might want to do is take some rotor and pad temps with a infrared pyrometer like we did when testing my G35. If you see temps that suggest the system is close to being overloaded (which I expect it probably is), then go a bit bigger so you've got some buffer. As your car continues to get faster, you will need better brakes to consistently slow it down. If you find your brakes are borderline based on temps, then go up to the Skyline setup and retest.

Or maybe you just don't brake much :)

[ADAM]

head weasel dave,

skylines are exactly the same as 300zx..they even use the same pads..rotors are 1/2 inch larger in diamter thats it...


so i might as well get the $400 conversion....see how that goes...get the car going faster..then when money permits get the crazy $2900 brakes..if they are needed..

[MazdaMatt]

knockback is an issue of hubs, rather than brakes, no? My readings tells me that if you don't fix your hubs, larger dia rotors will just mean the pads are pushed further back.

Adam, when you can confidently get on your brakes, your temps will go up!

[ADAM]

cant change the hubs..new ones do the same thing...

yes temps will go up ...he he

I think they will be fine..if not..will get better brakes

[Dave]

From what I understand, knockback is a hub flex issue. From what Andrew was telling me, changing the wheel bearings regularly can help, so maybe you need new front wheel bearings, Adam, to go along with those knockback springs?

Regarding rotor size and heat issues (which don't appear to be a problem for you yet), a half inch increase in diameter like that Skyline setup isn't insignificant when you think about how much mass and surface area you're adding for heat absorption and dissipation. Since the rotors do about 80% of the work with regards to absorbing, storing, and dissipating heat (through radiation, convection and conduction), going up to the Skyline rotors and calipers should improve heat control a lot more than you think, if/when you actually start having a heat problem.

[kmorris]

Adam is your problem that the brakes are fading or that you just can't get the amount of pressure you need (you mention adding a booster)? Maybe you need to go to smaller master cylinders (to generate more line pressure). That won't help fade or knockback of course.

Just a thought.

[ADAM]

have new hubs dave... on my second set this season...

Kmorris
the brakes are not fading...they are being knocked back..meaning the pads are being pushed away from the rotor as the rotor is deflected during hard cornering...

after every hard corner I must pump the brakes up to re seat the pads against the rotor..once they are seated they are not fading out (I have had brake fade before so know what that feels like) this is very different

[Andy]

Adam, you do not necessarily need to machine your calipers to fit knock back springs. If there is enough room behind the piston just install the springs and away you go. Knock back springs are designed in such a way that when they are fully compressed their size is equivalent to the wire thickness. So as long as you have enough room to install your pads with the piston fully retracted you are good to go. You may want to experiment with different spring rates.

Andy

[Slowpoke]

Are you locking up yet while braking? If you have no fade, would a HT-14 improve your stopping distances enough? At Mosport, a left foot tap on the straights is no big deal, but at a crazy busy place like TMP, the DDT or maybe even Calabogie, I can see the desire.

We seem to have solved the terrible '04 STi knockback issue by upgrading to Bigger '05 Hubs and bearings. Need more testing to be sure.

[ADAM]

yes..mosport is no big issue...

but smaller tracks like DDT are just nuts to drive on


Andy...

do you know where I can get these springs locally?

Adam

[Andy]

Adam, contact Rotora at 909-590-1712 ext. 102. You should know the diameter of your pistons before you call. This company also has some nice brake kits. We run Rotora brake systems on our race and street cars and are very happy with the performance. They also have a wide variety of OE replacement rotors and performance pads.

Andy

[philip_240sx]

Adam,

When I modded the brake pedal pivot point on your car for manual brakes, I allowed for the option to go back to stock. Switching to back to power assisted brakes should be easy.

You have a couple of options for brake boosters and M/C as you already know. ABS brake boosters for the 240 are a bit bigger than non-ABS version IIRC.

Unfortunately, I don't know of any wheel bearing upgrades. It appears all 240's use the same size front wheel bearing.

[Pete@Marcor]

I don't actually agree. The 300ZX pads and rotors might be the same size as a GTS-T Skyline, but I think that the GT-R Skylines use a differnet pad and somewhat larger rotor.
