Rear Proportioning Valve Options

[BenNC]

I've seen a few posts that mention replacing the proportioning valve for the rear brakes with a "tee".

1. Is it safe?

2. Is it street legal?

3. Is it useful if I'm retaining the stock brakes?

4. What is involved besides simply replacing the valve with the tee?

Thanks,

Ben

the tee is usually installed after a front brake upgrade like the BMW calipers. After that kind of a change the bias is all messed up, so removing the prop valve "may" correct it.
I do not recommend removing the prop valve with completely stock brakes.
The tee fits just fine, no real bending or modifications necessary.

BTW, for the street, the back brakes should not lock up in a panic stop in a straight line on dry pavement.
if it's set up that way the car will achieve better stopping results, but it will also make the car less safe in the hands of a novice.
many times a panic stop is attempted in a corner, or the driver trys to turn and panic brake at the same time. If the back brakes are locking up, guess what happens? the car turns into a maytag.
So, the safe way would be for the rear brakes to not be able to lock up unless traction is limited.

Having said all that, most of the people here would have no problem with more rear brakes than normal, but "this aint your ordinary party crowd. there are professionals here"
