    Not when equipped with factory disc brakes. Some might read this & come to an incorrect conclusion. This is why it should be clear on when the RPV is required & when it is NOT.

      Disc conversions with firewall master cylinders do not require a rpv, even if it was regular brakes to begin with.
      I can't believe that ever since way back at Post #6 this has been clearly explained and also Quoted in Posts: 7, 11, and 12 BUT it is still misunderstood!

      Quote: "If it is a Disc. Brake '63-'64 GT Hawk with the under the floor stock, single M/C it has NO Residual Valve or rubber seat and needs to stay that way"

      Here is another incorrect Statement, from Post#3:

      That pictoral on my site is for a Turner Dual Master for a GT Hawk with disk brakes. The Factory Disk brake (single circuit) master cylinder had NO RPV (residual Pressure Valve) at all, but the rear brakes were not like yours. Larks have self energizing brakes, Hawks did not.

      I am sure Bob Johnstone knows better, but this just came out wrong somehow.
