Re: Brake proportion valves

Can you re-phrase your question?

This is the answer to what I think you're asking. You'll need to know what kind of rear-brakes you have. There were 3 different size drums for all models 80-87. (You don't specify which year yours is.) If you give your parts supplier the RPO code from the inner fender or the glove box, they should be able to get you the right proportioning or combination valve.

This info came pretty much out of a Chiltons, which I recommend. Or a Haynes or whatever.

Lots of good info in idiot books.

Good luck-

-Todd

Re: Brake proportion valves

Are you refering to an "adjustable" valve? These are an "add-on" thing, they do not replace the original.
