I have a 1973 Scout II that I had front drum brake and converted them to disk. I did not install a power booster, and installed a new stock master cylinder. the problem I am up against is I have no peddle at all. I am wondering if I should purchase a master for a 1974 scout II with disk brakes cause the reservoir for the front brakes is bigger in that master or any one have any suggestions or have ran into the same problem as I am having? thanks
