Does anyone know of a good source for stock replacement proportioning valves or better yet, rebuild kits for them? I don't want to go to a non-stock style, and 30+ year old O-rings make me nervous. |

AFAIK there are no rebuild kits, nor are there secret stashes of new ones. They are not hard to disassemble, clean and "rebuild" with new premium O-rings; the harder part would be chasing down the premium O-rings. Plumbing supply house items will not be acceptable. I'd probably use Neoprene A/C O-rings. What kind of car are you working with? What kind of rear brakes have you got? |

One of the brake places, either mpbrakes or ssbc (wasn't there one other major one?) had stock style ones that would fit in same location w/same bracket If you have no luck at the brake places try finelines or classictube, inlinetube or other line vendors. Like i said, I know I saw them, just not positive where. |

Thanks Dan. It's a '71 Plymouth Satellite w/ stock disk/drum brakes; the origonal PV valve I've got in there is working just fine, but as since everything else in the entire system is new and/or rebuilt, it's probably the weakest link. While the O-rings are probably not hard to find, the plastic differential pressure switch insulator is a bigger concern, and I was just wonderning if somebody made them and so I could buy a spare or a kit. I've a book at home to tell me fluid/material compatibilities - I believe natural rubber is one of the preferred materials for DOT3, but I don't have the book in front of me. [I've been running DOT5 for years w/o trouble but have not tested viton compatibility with it; some know combinations swell badly.] |
