brake prop valve adusting, any experience doing this? Options

[Trekkor]

I still have the stock proportioning valve in the car.

I think the brakes favor the fronts a little too much.

I smoke the fronts, never the rears.

I'd like to put on some junk tires and see if I can get to the point where when I apply max brake pressure, the rears lock just after the fronts. (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Anybody try this experiment?

James, I know this isn't a "T" thread... but just the piston size of front versus rear is not the whole picture. Weight transfer plays into it as well as age/variance in pad compount/tire compound/etc. And putting a T on a stock system is an argueably bad piece of advice. my own personal experience of a stock race car with a T resulted in leaving the track at 75mph backwards. not something I would want to recommend to many people. But overall I do agree that a T allows more rear brake... just too much more for a stock set up. brant

Well, I did say "static front bias". I'm not advocating anyone fit a tee, only that you will have front bias with one. Whether or not you can use one depends on a huge array of factors, including your tires, your pads, your ride height, what suspension you run, how much gas you have in the car, and your driving style. All due respect, but lots of people run tees with otherwise near-stock brakes successfully. As always, one needs to be careful when making any changes substantial setup changes to brakes or suspension.

I would advocate running an adjustable prop valve over the stock unit. Even if you have to run it open, they're much smaller and lighter than the stock unit, and a tee isn't a whole lot lighter or smaller.
