What is the Shuttle valve??

[Legendary]

When I did my rear disc conversion my PV broke when I was trying to tighten the Tee in to it. So we bypassed it and put the lines right into the Mater cylinder. I email Matt (the brake guy) asking him if this was cool and he said he would recommend putting the PV back on because of the safety features of the Shuttle valve. What does the valve do and I'm I in danger driving the car?

It separates the front from the rear brakes. If either half of your car, such as say, your rear brake line blew out, you would still have front brakes so you could stop the car instead of all the fluid just getting pushed out the rear.

If it were all one, you would not be able to stop because you have no line pressure.

I see!

As I have it now, the two front lines are t'd to the master cylinder rear out put (for the front brakes) and the single brake line to the front output of the MC with a summit adj valve.

I guess I should get the PV replaced asap. **** happens and I don't won't 'brakes going out' to be on the list.

Good idea, get a new one asap.
