Bump . I used information in this old thread to solve my problem . I too put on a disk brake kit from Charlie and had one leaking hose to caliper fitting . I annealed three copper washers and used two of them between the hose banjo fitting and the rebuilt caliper , and one under the banjo bolt head . ( so one extra washer ) . I also tightened the banjo bolt much tighter than I thought would be necessary . I also used just a little , thick , anti-seize compound on the surface of the used caliper where the copper washer must seal . And yes I know that no sealer should be used here but desperate situations require desperate measures .
