is that like a proportioning valve? Give the 60/40 braking on the
front/rear?

Re: Working on Brakes (especially Rear Drums) - TJ
Exactly. A combination valve is also called a proportioning valve. It
distributes the braking power heavily to the front brakes and
much less so to the rears. On a TJ, the front brakes do the lion's share of
the braking, probably 80 to 90%.

Re: Working on Brakes (especially Rear Drums) - TJ
Yes.
It is a bit more complicated than just a 60/40 split. On pickups and
Jeeps it really tries to never lock the rears while keeping braking. It
plays with the pressures.
