Cadillac 2008 SRX - Manual (Page 320)

It is not a good idea to top off the brake fluid. Adding
brake fluid will not correct a leak. If fluid is added when
the linings are worn, there will be too much fluid
when new brake linings are installed. Add or remove
brake fluid, as necessary, only when work is done on
the brake hydraulic system.
{ CAUTION:
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work is done on the brake
hydraulic system. See “Checking Brake Fluid”
in this section.
When the brake fluid falls to a low level, the brake
warning light will come on. See Brake System Warning
Light on page 3-38.
Refer to the Maintenance Schedule to determine when
to check the brake fluid. See Scheduled Maintenance
on page 6-4.
Checking Brake Fluid
The brake fluid can be checked without taking off the
cap by looking at the brake fluid reservoir.
The fluid level should be
above MIN. If it is not,
have your brake hydraulic
system checked to see
if there is a leak.
After work is done on the brake hydraulic system,
make sure the level is above the MIN but not over
the MAX mark.
