I've been fighting mine. So much that I was tempted to dump it and go with just an adjustable proportioning valve.
But then I read some really good info on the superiority of having the combination valve with the warning light and metering. The combination valve supposedly has the ability to 'meter' the front and rear needs for different braking circumstances.
If I was driving 30 and gently applied the brakes, the weight shift to the front wheels is a lot less than doing 80 and slamming on the brakes.
Each case would require different pressure to the front and rear. An example using arbitrary numbers would be as an example of gently applying brakes would be 60/40 (front/rear) But when you slam on the brakes, more weight is shifted forward to the front wheels. Meaning the rears will lock up at even less fluid pressure to the rear.
Supposedly, the metering valve can adjust for different situations.
Whether it does or not, the physics of varying required rear fluid pressure makes sense.
So eliminating the combination valve and replacing it with an adjustable one isn't recommended.
