pv68 right stuff valve operation
oh hey,
I'll spare you a re-read of my old brake post and just ask the new question outright. Just wondering if anyone knows if the pv68 valve is suppose to move back and forth when i press the brake pedal? my assumption is no. Probably only suppose to move under a massive hard braking event? Does anyone know? The master cylinder shouldn't be pressing more pressure than normal. it's he right model. it's leaking fluid out of the back of the valve every time i hit brake pedal mildly. thank god i didn't drive it out of driveway. I'll call right stuff tomorrow and ask. Here is a picture and a video. https://youtu.be/6hr39LvrKJo really appreciate any help. I phoned the muscle car shop that sold me this and all they could say is they gravity bleed those and never an issue. I couldn't even send fluid through it without pressing the button . so i dunno all things lead to this being defective. of course. feeling bummed.
