        gathering parts

        I've been waiting for one of my final piece I need for my Cobra front bake swap. I'm swapping the front brakes on my 1986 SVO, I have a few more parts to go.

        Time to upgrade

        Upgrading my brake system, so I decided to go ahead and install disc brakes on the rear and brought this as an upgrade.

        93 cobra master cylinder

        fit/finish is great.install was straight forward.if going from stock 5.0 you will need to do a 3-2 line conversion but otherwise easy-peasy.also a good idea to check booster rod depth before install

        Master Cylinder replacement

        Night and day braking! The unit is a direct fit and did not require modifications in my application. The result is a much more solid pedal feel. I would recommend anyone with a fox mustang upgrade as the stock unit does not compare.

        Master Cylinder Upgrade

        My boys and I are doing a build-up of a '84 Notchback. One of the upgrades was replacing the rear drum brakes with new disc brakes. This upgrade required a master cylinder capable of producing greater fluid volume/pressure. With a larger bore this master cylinder is perfect for the job. This product works perfect!

      One of the reviews said to do a 3-2 conversion when installing on a stock vehicle.what is a 3-2 line conversion? Thanks, Wayne.

      • It looks like what he was referring to was a 3 brake line to a 2 brake line conversion. There should be no need for this since this is a direct fit replacement and should not need any modification.
