Brake Master Cylinder
Your brake master 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 brake fluid
goes down to an acceptable level during
normal brake lining wear. When new
linings are put in, the fluid level goes
back up. The other reason is that fluid is
leaking out of the brake system.
If it 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, it isn’t a good idea to “top off’ your
brake fluid. Adding brake fluid won’t
correct a leak. If you add fluid when your
linings are worn, then you’ll have too
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.
When your brake fluid falls to a
low level, your brake warning light,
“SERVICE ABS” light and “SERVICE
ASR” light will come on. Also, the
anti-lock brake and Acceleration Slip
Regulation systems are disabled. See
“Brake System Warning Light” in the
Index.
What to Add:
When you do need brake fluid, use only
DOT-3 brake fluid
- such as Delco-
Supreme
1 l@ (GM Part No. 1052535).
Use new brake fluid from a sealed
container only, and always clean the brak
fluid reservoir cap before removing it.
