Chrysler 2008 PT Cruiser - Manual (Page 408)

Master Cylinder - Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the brake system warning light indicates system fail-
ure.
Check the fluid level in the master cylinder when per-
forming underhood services.
Clean the top of the master cylinder area before removing
the cap. If necessary, add fluid to bring the fluid level up
to the requirements described on the brake fluid reser-
voir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Fluid level can be expected to fall as the brake pads wear.
Brake fluid level should be checked when pads are
replaced. However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only manufacturers recommended brake fluid. Refer
to “Fluids, Lubricants, and Genuine Parts” for the correct
fluid type.
NOTE: If your vehicle is equipped with a Manual
transaxle , the Brake Fluid Reservoir supplies fluid to
both the Brake System and the Clutch Release System.
The two systems are separated in the reservoir and a leak
in one system will not affect the other system. The
Manual Transaxle
Clutch Release System should not
require fluid replacement during the life of the vehicle. If
the Brake Fluid Reservoir is low, and the brake system
does not indicate any leaks or other problems, it may be
a result of a leak in the Hydraulic Clutch Release System.
See your local authorized dealer for service.
Use only manufacturers recommended brake fluid, refer
to Fluids, Lubricants and Genuine Parts for correct fluid
type.
