This adjustable proportioning valve and distribution block from Aeroflow Performance allows you to run lines from the brake master cylinder to the block and then to the appropriate wheels. What is neat about it is that it also contains the proportioning valve and brake light switch. This dramatically reduces the number of fittings needed and potential leaks. It can be mounted vertically or horizontally directly underneath the master cylinder or as a standalone unit elsewhere on the car.
The adjustable proportioning valve regulates rear brake pressure, with an easy to turn rotary handle with directional arrows makes it simple to either increase or decrease rear brake pressure. This valve helps to regulate rear brake pressure and help maintain correct brake bias between front and rear.
The distribution block connects to the master cylinder and distributes brake fluid to all four wheels. This block accepts 3/16" brake lines and the inlets and outlets on this unit are 3/8-24" inverted flare females. It has two inlets from the master cylinder, two outlets to the front brakes and one outlet to the rear brakes. A cool feature of this distribution block is the built-in brake light switch. This brake light switch allows you to activate your tail lights with hydraulic pressure from your brake system.
It includes five stainless steel 3/16" fittings and wiring pigtail for rear brake light switch.
NOTE: This is not a direct factory replacement for original blocks. Some line modifications may be necessary.
