    I went to 2 different autoparts stores tonight and they wont sell me a proportioning valve. They say the liabilities that go with that part makes it so there are very very few aftermarket makers of one.
    Anybody else run into this?

    as a parts store manager I got that question all the time, yes they are not offered... not a part that would want reman'd anyways. the only place you can get them would be a year one or brothers type place, i'm not even sure if LMC would offer one.

    actually i was talking any style.

    #1) i just converted to 4 wheel discs.

    #2) i bought new booster, m/c, and calipers, so i thought might as well replace it all.

    #3) My brakes sucked before the conversion, so i thought rebuild it all. I just couldn't beleive i couldn't get one. I looked at jegs and all the adjusting ones look weird. They only have 2 lines. Does this mean i need one for the front and one for the back?

    There are FAR too many factory ones for the parts places to stock them, plus they rarely go bad.

    Your local speed shop, that sells go-fast parts for the racers and ricers and muscle cars, will have the SSBC or the Wilwood or something in an adjustable aftermarket.

    I got the SSBC from my local place (also happens to be a great parts place :D )

    Keep in mind that the wilwood p-valve is not a pressure regulator like the one on your cutting torch. It limits rear pressure to ~57% of what ever the front pressure is, IF that pressure is above the "knee point" of the valve. If the pressure is below the knee point then both pressures are the same.
    What you adjust in turning that knob is the position of the knee point, not the pressure percentage.

    Stop-Tech has an excellent article on P-valves.

    You can get the same one inline tube sells, from gmpartsdirect.com for alot less money. It is a 4 wheel disc unit. I thik I paid 109.00 with shipping.


    And yes, local parts stores don't sell many parts that have an extremely low failure rate. The original manufacturer has to make sure that a safety item like that is built to last in the first place.

    Brakes are way over rated anyway, all the do is tend to slow you down. :haha:
