Today I started filling the brake system but after filling left side a slow leak was noted coming from the parking brake again. Dratts!! On inspection the fittings all looked clean and leak free. So I drained fluid and once again removed the parking brake from the lines. It was wet in between the two body pieces which tells me the leak was internal issue. Took the assembly apart and noticed a couple small pieces of black rubber on the cam. Magnifying glass confirmed that the rubber o-rings had been sliced. Probably due to the dissassembly and reassembly process I managed to harm the 4 o-rings and they now leak. So.... I can either buy a rebuild kit or try to find the same size 1/4 x 3/8 x 1/16 rubber nitrile rings locally before I can try again.
