When I resealed mine, and at subsequent system bleeds, I used a small jeweler's screwdriver to center the shuttle inside the valve. I couldn't seem to center it by using the pedal, as the instructions say.

Does it serve any purpose other than to inform the driver of the obvious "you've just lost half your brakes"??<br>My understanding is that PDWA simply provides a ground for the warning bulb, such that it illuminates when you've had a sudden loss in either the front or rear brakes. It won't provide any help though, right? ?I doubt the driver will even notice that the light has illuminated, he/she will be too busy looking for a safe way to bring the car to a stop!?<br>Tim Holbrook1971 TR6<br><br><br><br>On Thursday, June 1, 2017, 6:55 PM, Bud Rolofson via 6pack <6pack@autox.team.net> wrote:<br><br>The switch doesn?t actually (and was not intended to) seal anything in the PDWA, the o-rings on the barbells internally seal the fluid in the PDWA.
