Got one, going to try to put it in today, but instructions say nothing about if it is ok to mount vertically or does it have to be horizontal. Not sure what is inside that thing and if the valve would be affected by the direction of installation or not. Figured someone here would know.
OK, cool! Took the car for a drive yesterday, brakes worked great! Did not go to the floor, just most of the way then firm stops. So I am pretty sure this valve will fix stuff. The only problem is I cannot keep the ET Street slicks planted on the road. The rear end is constantly sliding side to side when I gun it. May have to put the street tires on before we come to the Annual meet.
You shouldn't be running any residual pressure valves with 4-wheel disc brakes unless it was a car that had the master cylinder mounted under the floor.
When I let off the brakes, the springs back the pads off too much, and pushes too much fluid back into the M/C. So the first pedal goes about half-way down before pressurizing. Was hoping this would hold the brakes closer to an engaged position so it would be firm on first pump.
Once you get it mounted and bled, just check to make sure that the wheels spin freely once you release the brake (2 person job). A slight pad to rotor touch is OK, just no dragging.
We ran 2 blue residual valves in the stock car on 4 wheel disc brakes- I've had them mounted both horizontal and vertical - didn't matter but you will find arrows on them for direction of flow towards the brakes and they have to be mounted that way - they are only 2 pound (red ones are 10 pound for drum) check valves so the arrows are the most important thing
