Replacing the rear proportioning valve with a tee fitting???

Will this make is brake more during autocross?

And, is this a standard plumbing tee, or is it special???

Tons of info in the archives (search) -- first questions are, do you have stock brakes? Tires? Track, autox or street car?

The tee itself is a brake specific part; most use a VW tee available for like $10-20 at typical bus/bug shops.

I have searched, no quality results...

We need a better search engine.

Thanx for the response.

Rich,
I just installed one, got it from someone, who bought it from James Adams....
available at ANY big shop for under 10 bucks...

think of it as a P -valve that is wide open....
gives MORE power to the already undersized rear brakes

is this tee fitting a stock part on a beetle???

I have two out in the barn...If I can steal it, that would be good.

stock brakes, no T ...

bigger brakes and MC, the T will give you more bias towards the rear, which is a gud thing as bigger brakes tend to favor the front.
key is, you want the front to lock up just a millisec before the rears and not the other way round.

the "Tee" can be had at every VW-Bug shop for $5+ ...

An adjustable proportioning valve is the best way. I am doing one in cab like the pic. The trick has been finding one with all metric connections, found at PMS.

Marv,

why go with the handle type when it only has ~6 positions, why not use the knob type with infinite adjustability????

Cuz the range of adjustment is the same in both types of P valves, this type lets you know where your at by touch or visual.

except, unless you've got HUGE rear brakes, we always end up running the adjustable proportioning valve "full open" which is exactly what the $5 "T" does for you ...
