Let's Play guess that part!!!

I can't figure out what the proper name of a brake part under the car is to find a replacement. It's sometimes refered to as a combination valve, Byass Valve, and 1 piece switch, which is inline with the brake system that controls the pressure of the rear calipers and what makes them grab just before the front ones. I CAN'T FIND ONE ANYWHERE and I don't know if i'm calling it something wrong or what. Does anyone know what this part is called?

metering valve?

Well, there's a check valve in between the brake booster and the intake mani and there's the proportioning valve, which is actually built in to the master cylinder.

From your description, it sounds like you're talking about the proportioning valve.

They grab at the same rate until you hit the proportioning valve's split point. Then pressure is gained at a faster or slower rate on one set of calipers depending on the valve.

That component is built into the master cylinder.

If you are looking for a simple adjustable pressure valve, you can get one from Wilwood and put it inline.
