One more thing, a proportioning valve limits fluid to a brake where this 
adjust and balances pressure. A balance bar system is not only ideally 
much better then a proportioning valve but this is especially true if 
you don't have a booster.

This system is something anyone who can change spark plugs would love.

I have the dual MC balance bar on my car. Like amny things on my car 
when I got it, it was installed but not adjusted. It was locking up the 
front brakes way too soon and would slowly skid to a stop. It was bad. I 
had no question I would rear end some one because I couldn't get the car 
to stop for nothing.

We all know the fronts have to lock up first but if they lock up too 
soon the backs won't help the fronts as all and the tires may as well be 
card board boxes.

Balance in braking is everything. The balance bar was EASY to adjust. 
Loosen up locking bolts, move threaded rod, tighten locking bolts.

It took me a half hour of playing to get the brakes adjusted. Move the 
bar, take it out lock the brakes, go back and adjust some more. Everyone 
knows you want the fronts to lock first but in order to find the 
threshold you have to take it too far. I adjusted it to where the backs 
just started to lock up, then adjusted it back across the threshold 
where it was front bias.

After that I the fronts still locked up first but the car would plaster 
you in your seatbelt. Awesome and easy set up to use.
