Brake Master Cylinder Your brake master cylinder here. It is filled with is DOT-3 brake fluid. There areonly two reasons why the brake fluid level in your master cylinder might go down. first is that the brake fluid goes downto an The acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. other reason is that fluid is The leaking out of the brake system.If it is, youshould have your brake system fixed, since leak meansthat sooner or later your brakeswon't a work well, or won't work at all. So, it isn't a good idea to "top off" your brake fluid. Adding brake fluid won'tcorrect a leak. you add fluid when If your liningsare worn, then you'll have much fluid when you get new too brake linings.You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system. 270
