  • disc brake conversion

    I am in the process of putting disc brakes on an 800 with an s2 axle. The hard lines on the 800 are smaller than the s2 hoses for the discs, the connection I mean. Is there a known line application that will fit this such as a CJ5 with discs or do I have to fab up some connectors? This is not what I want to do and I am sure someone else has done this conversion.

    I have seen one done and they just ran a new line from the master cylinder down to the front axle in the middle with one flex line. Then had a hard line to each wheel. It worked great when flexing suspension. The reason I say that is the stock master cylinder will not be able to handle the new calipers on disc brakes and I have never seen discs without power assist.

      In 1967 I bought a Plymouth Barracuta, 383 V-8, 4 Speed, with Disc brakes...no power booster (no room for it). Higher peddle pressure than power brakes, but great feel and good stopping.

      Now that I think about it, non-power disc brakes might be just the ticket off-road........

        That may be the option to have a proper master cylinder for disc's?
        Eric just did rear disc brakes and the stock Scout II would not handle them.

        Whatever does happen we are talking about brakes, talk a lot to the counter man and even some e-mails to the manufacture.

          I like the idea of running a line to the front and then going to the wheels with a hard line, however how do you hook up the hard line to the calipers? Discs have a block and bolt thing not a line into a wheel cylinder. I think from past experience that if I remove the residual pressure valve the stock M/C will be fine. There are many OE systems with non power discs so I don't think that is a problem. Thanks for the input it is a possibiity.
