If you pull the cap off and look at the mating surface of the master you will notice it is cast and has small indentations. This is how I fix them when they leak. Remove most of the brake fluid from the master. The wifes turkey baster works good. Then fill the master with rages. Then with a pice of 2x4 and sone sandpaper start to sand the top lip of the master till most of the casting pits are gone. Then you are good to go. I like to do this before instalation. Then I just turn it up side down on the table with a pice of sand paper on the table and start sanding. And yess you can tightin the bailing strapes. Good luck.
