    To tell you the truth, I don't remember. But I do remember going out driving and nailing the brakes hard. I kept restricting the rear brakes until they stopped locking up. Haven't touched it since. :2thumbs:

    The ones I have done ended up being all the way in (full restriction).

    All my brake stuff is original equipment from 1970 as far as I can tell. Flex likes etc... My car was converted to the 73-74 spindles and disc breaks before I bought it. I have never driven my car yet. That being said I'm replacing my flex lines( Russell braided lines),wheel cylinders,and calipers, when I replace the master with the Dr.Diff unit. I'm liking the wildwood one that Bullitt posted!( Thanks Wade!  :wave: ) I have a brand new Wilwood single in/out adjuster from a past project . Money aside( it's not thats expencive) which way should I go? I'm just thinking I should replace everything from the original 40 year old system in the name of safety? With the investment I have in the car now what's another $60 I'm thinking? Any opinions on that out there?

    If you're replacing everything, you can go with the dot5 fluid shadango was talking about. From what shadango said it doesn't eat paint, thats gotta be a plus.

    ARe you replacing all your steel lines too? If not they need flushed to use the Dot 5.

    Me, I am keeping mine as they are in great shape......not sure if they are original or what but they look real good.

    See my other post about DOT 5....I read a lot of negative stuff about it......I figure Dot 3/4 have been around forever and works well aside from the eating paint thing....

    (Coincidentally....I thought brake fluid would help diossolve the old undecoating caked on my k-member splash shields?  Huh....not even close.)

    Any one running or have any experience with a line lock for locking up the front brakes?

    Well, if the prop valve you have works, I'd say use the valve and adjuster you have. If you have reason to be suspicious of your present prop valve, go with the one Bullitt posted. :2cents:
    By the way Brads70, are there any decent chrome shops down there at that end of the province?

    I have no idea how/if the p-valve works or not? I haven't driven the car before? If its for a drum/drum car shouldn't I change it? I guess for the sake of $60 I should change it?  :dunno:
    Sorry I don't know of any chrome shops?  None in Barrie, I'd guess maybe in Toronto?

    FWIW my disc/drum prop valve doesn't look quite like that. Might want to replace yours with a disc/drum unit? Not that I know the difference. Plus the new one will be NEW! Shiny brass.I need to re-do my M/C,factory prop. valve. :icon16:  Oh... And I'd like to know about the front line lock too... :popcorn:

    From what I understand, we drum/drum people have distribution blocks, not proportion valves, stock -- and we dont need the stock style valve if we are going with an aftermarket unit in the rear line like a Wilwood.  :2cents:

    :popcorn: we are both in the same boat with the same parts at the same stage! LOL
    This is what I have now on the car ,can anyone ID it as a drum p-valve or a disc-drum p -valve? Sorry don't mean to hijack your post , just thought seeing as we are in the same boat sharing info would help us both? :2thumbs:




    Just referred to the factory manual to double check.....according to it, and going by your picture, we both have a simple brake warning switch....it is not a metering or proportioning valve.
