When new linings are put in, the fluid level goes back up. otherreason is that fluid is The brake leaking out of the brake system. If it is, you should have your system fixed, since a leak means sooner or lateryour brakes won't that idea to "topoff' your work well,or won't workat all. So, it isn't a good brake fluid. Addingbrake fluid won'tcorrect a leak.If you add fluid when your liningsare worn, then you'll havetoo much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system. 272
