Brake Master Cylinder
Your 13min: muster Cylinder is here. It is ﬁlled with DOT-3 brake ﬂuid.
There are only two reasons why the brake ﬂuid level in your master cylinder might go down. The ﬁrst is that the braid: ﬂuid goes down tu no aeeepuihle level during; normal brake lining wear. When new linings are put in. the ﬂuid leyei goes tlﬂﬂl'i. up.
The other reason is that ﬂuid is leaking out of die brake system. ll‘il is, you should have your brake system Fixed. since a leak means that sooner or later your brakes won't work well. or won't work at all.
So. il isn‘t a good idea to "top off" your brake fluid. Adding brake ﬂuid won't. eurreei a leak. llynu add ﬂuid when your linings are worn. Ihen you‘ll have [no mueh ﬂuid when you get new broke linings. You should add (or remove} brake ﬂuid. as necessary. only when work is done on the hrdlie hydraulic system.
It you have too much brake Hold, it can spill on the englne. The fluid will burn it the onnlno ls
hot enough. ‘thu or others oould be burned. and your vehicle oould be damaged. Add brake fluid onlyr when work is done on the brake hydraulic oyolen'l.
When your brake ﬂuid falls to a low level. your brake warning lighl will come on. See “Brake System Warning Light" in Lite Index.
What to Mid:
When you Lll} need brake fluid, use only DDT-3 brake ﬂuid—such as Delco Supreme li‘ﬁi lGM For: No. 1052535}. Use new brake ﬂuid from a sealed container
