Fastest reacting brake for a .400 pro tree - 01/23/14 02:31 AM
What is the best transbrake valve body for .400 tree racing?
I am currently running a tranzact pro brake in my 904. I can cut .01 and .02 lights consistently with it, but on a .400 tree, they are always .100 slower....not saying its the brakes fault, but I am not sure if the brake is meant to release for a .500 tree because I can't get ahold of Joe at tranazct for the life of me about anything
So, does anyone know what brake is best for this kind of racing? Or do I already have one that works well and need to just work on my reaction times?
Thanks!

What button...front tire pressure....front end limited?...there are quite a few other easy and almost free things you can do.

Take the fronts to 45 if they will handle it.
Ditch that button for one from Grainger...I'll get you a part #
Tighten up the travel as much as you can and still get weight transfer..
What size are the front tires?...run as small a tire as you can.

IMO the best and quickest brake is the Griner. I was able to go 430's in a heavy leaf spring car with it, shallow staging like I did bracket racing( and I am an old grandpa with probably slow reaction)
The Transact is actually a Griner knockoff, believe at one time Joe worked for Griner.
I ran the Griner for years, never an issue, no creep, and it was consistant.

If you can put a 25" front on that would help...the increased tire pressure will decrease the rollout...you can drill and thread the hole for the bump stop and put a bolt in instead with a bumper on it making it adjustable.

Can't get Joe? Oh come on 317-846-4933. I call him at least once a month just to catch up. I think everybody does. Maybe that is why he hasn't answered you.
The TRANZACT is not the same as Griner. Joe left Griner years ago. He has significantly changed his brake design several times sense then.
I ran the regular brake and cut awesome lights. I later ran a Pro Brake from TCI that Joe makes for them. No one beat me on the tree with that brake. I actually had to slow myself down to not red light.
Get a delay box with a reaction timer program in it. If you cannot go .180 you either have a button problem or you are simply slow.
#1 Your front tire pressure is too low
#2 You may be too low on rear tire pressure
#3 You are pushing your button too hard.
#4 You have a limited amount of springs in your high gear clutch pack install all 15 and get the better springs.
#5 You may be running stupid line pressure and have a pressure tank instead of a transmission. The same adjustment on a 904 will be 25-35 lbs more in a 904 than a 727. Check your line pressure. 135 is plenty

The fastest brake you can get is the one being operated by a twenty something driver.
If they'd had trans brakes 40 something years ago I bet I would been GOOD.

That switch is adjustable...you can use washers...take all the plungers travel out with that switch and you will see you BARELY have to put any pressure on it and there will be almost no travel on the release.

If you look at the picture of the switch you just want the very top of the button exposed. You will see it is a two stage travel...one is a very small movement...the second is the whole length of the shaft. You want to shim it to the first stage. Mine is though a hole in the steering wheel...get creative..

It's not your break. I have a tranzact pro break and can go red during the daytime. Night time I need to really focus to stay green. I run my Valiant in the 6.50 index stuff all the time.

turbo-action brake is slowest, griner is a touch quicker then A&A, had to go to a 24" tire to do double "0" lights
