Personally, I think there are better was to make your car turn than shuting off the right front brake. What happens when something happens if front of you, and you get on the brakes to avoid it, the car pulls HARD LEFT!! Run 4 wheel brakes and use springs and weight to make the car turn.

How many late models or modified do you see with brake proportioning valves in the cockpit? Almost all of them. If you can run the shut-off valve into the cockpit you then have an adjustment that you can make during a race if you are having troubles getting it through the corner.

I have always run 3 brakes and preferred it. It gives me another tool in getting through the corner. It lets you stay on the gas, and squeeze the brake, to run the low line. I did not find the "panic" stop to be a problem, just hold the wheel straight. As someone else said, you can use a proportion valve, and give yourself control of how much or little RF brake you want.

It takes a different setup than 4 wheel brakes. I personally like them alot. I think track type may dictate when to run them. They can be a handful on dryslick if you're not setup right. Braking isn't an issue once you're used to them.

set the car right and you can use 4 brakes it takes more time and effort but well worth it mine is a top 5 car every week cause i can stop when needed 3wheerlers don't take the time to set up right easery to do right the first time than replaceing a front stub

Right front brake cut offs are great for one thing - the make an awesome parking brake.

I put one on when I built my car, used it once in a race and have only used it as a parking brake since. In fairness though, I have a balance bar set-up to tune the front to rear bias, so if you couldn't have that, maybe the 3 wheel set up would be OK. I'd stay away from it, but thats just me.

Guys that have problems braking with a three wheel brake setup must also remember this...

What happens when you have your brakes cranked all the way to the rear on your balance bar??? You don't complain about not being able to stop there.

When putting a car together, I normally stick a small peice of pop rivot shaft in the brake line, the RF will still work a little, but not much at all. Any time you can have a RF shut off legally in the car, use it. You don't have all year to play with setups, you have 15-20 laps a night, and you can't stop the race to make a change. If your car is real tight in the center, what are you going to do in the car? The line is right on the bottom also, so you can't run high going in... If you adjust your brakes further to the rear you'll end up being real loose in and then tighter off..

Think about it guys, we aren't Nextel Cup cars that can make wedge adjustments, tire pressure changes, spring rubber changes during a pit stop.

First, I don't crank it all the way to the back. Second, with a bias bar, your moving pressure from one end of the car to the other. With a cut-off, your reducing it to one corner without increasing it to another.

Your right, it is hard to get a car driving right 15 to 20 laps at a time. However, its a lot harder to get it driving right when its sitting in the garage waiting for a new front clip. I've seen too many cars go right front first into stopped cars to use 3 brakes at a time.

Do what works for you.

ive never seen anyone wreck due to 3 wheel brakes. ive seen them pull to the left under heavy breaking but never wreck.

when its dry slick ill cut r/f off to keep running in hard and still stay on bottom, when its tacky ill run all 4..

its all about preferance, and getting used to the 3 wheel brakes..if you cant drive in the first place do not attempt the 3 wheel breaks. it takes a smooth driver to run them..

sc1 - nice little jab at the end there, LOL.

It also takes a smooth driver to drive the car through the corner instead of using the brakes to jerk it sideways.

I think it all depends on the car, driver and track. If the track requires you to be dead sideways in the corner to be fast, than maybe the 3-wheel deal is good. If its a smoother, faster track, than maybe the 4-wheel brakes are better.

Its fun to argue about this stuff.

that wasnt a jab at anyone...LOL

out of 30 cars at out track only 2 or 3 sling it completely side ways. and they do it to try to keep from getting passed. i can run in hard tap the brakes and go in perfect. only way i see 3 wheel brakes sling you side ways is if you wait to long to hit them or if you do more than tap them. not to mention if your car has a bad push you can leave foot on gas and tap brakes and come out turn with out getting completely off the gas..

call them a crutch or whatever..guess ill be satisfied with being a cripple...lmao

I think 3 wheel brakes kept a fellow racer from getting hurt bad a couple of weeks ago when a guy that was running the high line got real loose and i was on the low side and he came down the track on me, it looked like he was gonna gather it up so i stayed on the gas ( i had just passed 3 cars in that turn) but he didnt gather it back up so it was either t-bone him right in the driver door or stand on the brakes so i stood on the brakes hard the car turned left and i pancaked him and all we had was bent pieces on the car, then later at the paywindow i heard the guy tell his buddy that i never let off and wrecked him but he was the *****zz that didnt let off of the gas when he was spinnin out!!

I prefer the 3 wheel brake,havnt really had problems with a panic stop,But after a race a few weeks ago in my wife's stocker I will run 4 brakes,The track was almost impossible to drive with 3 wheel brakes,it had 'sealed over and even touching the brake made the car way to loose on entry.

Go with what works for you.

I would put a shut off on the rf and run about 1/2 pressure to start with.

Three will brakes are a crutch. I used to run them in my nova sometimes, then learned how to set it up a little better and did not need them.
As far as 3 wheel crash, I had one, i was on a half mile, entered the corner too hard and looped it and backed it into the wall. My own fault 100% it was my rookie year.
3 wheel brakes can help you get thru a night, but it is a crutch, and do some searching so you get the car right without them in time.
