Can we agree on restricted flow as pressure increases at the knee point?
GM did use a PPV on some all drum applications. Makes perfect sense to me. But ABS has changed all of this.
What I am trying to point out is that the ill-conceived notion that an ADJ PPV will correct all situations. That is why they are not approved for the street. Their function is race car only.
Some of these so-called "BRAKE KIT SELLERS" are dangerous (IMO).
